Explanation:
RrYy x 2
Answer:
9 out of 16 (also 9/16)
Explanation:
Count the likeliness of the offspring to be round:
RR, Rr, rR, rr
round shape is 3 out of 4 times
Count the likeliness of the offspring to be yellow:
YY, Yy, yY, yy
yellow color is 3 out of 4 times
Multiply the likeliness of being round and being yellow (since they are two independent probabilities, we are using multiplication rule):
3/4 * 3/4 = 9/16

1. What is a biogeochemical cycle?
2. What drives, or powers, the water cycle?
3. What causes water to condense and form clouds?
Answer:
1. In ecology and Earth science, a biogeochemical cycle or substance turnover or cycling of substances is a pathway by which a chemical substance moves through biotic and abiotic compartments of Earth.
2. The sun, which drives the water cycle, heats water in the oceans. Some of it evaporates as vapor into the air. Rising vapor cools and condenses into clouds.
3. Heated by sunshine, the ground heats the air just above it. That warmed air starts to rise because, when warm, it is lighter and less dense than the air around it. As it rises, its pressure and temperature drop causing water vapor to condense. ... The air cools as it rises, and eventually clouds form.
Explanation:
If a DNA strand contains 12% thymine, it also contains ____
a. 12% A, 38% G, 38% C
b. 12% A, 12% G, 38% C
c. 12% A, 12% G, 12% C
d. 38% A, 12% G, 38% C
Answer:
If G = 14, then C = 14 and G + C is 28. Thus A + T. The percent of adenine in a double-stranded DNA is 38. Therefore G + C = 100 - 76 = 24, and C = 24/2 = 12 percent.

matter and energy move through ecosystems between different organisms. how does matter travel through an ecosystem and through earths spheres?
Answer: In ecosystems, matter and energy are transferred from one form to another. Matter refers to all of the living and nonliving things in that environment. Nutrients and living matter are passed from producers to consumers, then broken down by decomposers. Decomposers break down dead plant and animal matter.

Explanation:
how is the law of mendelian inheritance violated in down's syndrome
Answer:
According to the Law of segregation presented by Mendel, each gamete receives just one copy of every allele randomly. Normally all the cells follow the Mendelian inheritance.
In Down's syndrome, an individual gets 3 copies of a chromosome instead of the normal chromosome pair. This is also known as trisomy 21. It does not follow the law of segregation of Mendelian inheritance as it gets three instead of two.

Why bacteria generally dies in the presence of oxygen ?
Bacteria that require oxygen to grow are called "obligate aerobic bacteria". Without oxygen they generally die since these bacteria require oxygen to grow.
Their methods of energy production and respiration depend on the transfer of electrons to oxygen.
1. Tell what type of interaction is being performed by the following pairs of
organisms. (Commensalism, Mutualism, Competition, Parasitism and
Predation)
6. aphid and rose plant
9. butterflies and flowers
10. birds and worms
7. lion and buffalo
8. coral reefs and fishes
Answer:
6. Parasitism
9. mutualism
10. predation
7. predation
8. mutualism
Explanation:
Living organisms, in their natural habitat, forms certain relationships with one another. These relationships are as follows:
- Mutualism is the association of two organisms in which both organisms benefits from one another in the relationship. Example is butterfly and flower in this question, where the butterfly helps pollinate the flower while the plants provide food source for the butterfly. Another example is coral reefs and fishes where the fishes and coral depend on one another.
- Predation is the kind of relationship in which one living organism called PREDATOR kills and feeds on another called PREY. Examples are the relationship between birds and worms, lion and buffalo where the bird and lion are predators while worm and buffalo are preys.
- Parasitism is the relationship between two organisms in which one organism called PARASITE lives on and derive nourishments from another organism called HOST. In the example of aphid and rose plant where the aphid is the parasite and rose plant is the host.
The type of interaction that is being performed by the following pairs of
organisms include the following:
Aphid and rose plant - ParasitismButterflies and flowers - MutualismBirds and worms- PredationLion and buffalo - PredationCoral reefs and fishes - MutualismAphid and rose plant have a parasitic relationship due to the aphids taking
up vital nutrients from the rose plant thereby resulting in distorted growth.
Butterflies and flowers have a mutualistic relationship as the butterfly aids
pollination of the flowers and also derives food and juice in return.
Birds and worms have a predatory relationship as the birds eat worms for
food and survival.
Lion and buffalo have a predatory relationship as the Lions eat buffalos for

Tongue Rolling is a one gene trait. So where is it’s chromosome and it’s location??
Answer: One type of map uses the cytogenetic location to describe a gene’s position. The cytogenetic location is based on a distinctive pattern of bands created when chromosomes are stained with certain chemicals. Another type of map uses the molecular location, a precise description of a gene's position on a chromosome. The molecular location is based on the sequence of DNA building blocks (base pairs) that make up the chromosome. Buttt I don’t know if this is the answer your looking for. But I hope this helps in a way.
Explanation:
refers to the Linnaeus' method of naming species
using a unique two-word name made up of the genus and species name.
O cell organelle
O level of cladistics
O binomial nomenclature
O method of taxonomy
Answer:
binomial nomenclature
Explanation:
Binomial nomenclature as the name implies (binomial = two, nomenclature = naming) is a system of naming organisms that comprises of two unique Latin word names. The binomial nomenclature is a system of naming that was proposed by the man referred to as the FATHER OF TAXONOMY, CAROLUS LINNAEUS.
According to this system of naming organisms, the two names are the generic and specific epithet of the organism respectively. For example, in dog, which is Canis familiaris, Canis is the generic name while familiaris is the specific name.
What is a phenotypic variation?
Answer:
Mendel worked with pea plants showing complete dominance for various characteristics
- E.g. flower color, plants either have purple flowers or white flowers
- A particular genotype produces a recognizable phenotype
Explanation:
Phenotypes can cause by genes, environmental factors, or a combination of both.
Phenotypic variation, then, is the variability in phenotypes that exists in a population. For example, all people come in different shapes and sizes: height, weight, and body shape are phenotypes that vary.
A 30-year-old male demonstrated a subtle onset of the following symptoms: dull facial expression; droopy eyelids; puffiness of the face and periorbital swelling; sparse, dry hair; dry, scaly skin; evidence of intellectual impairment; lethargy; a change of personality; bradycardia (60 b/min) low range of normal; a blood pressure of 90/70 low BP; anemia low iron – cant transport O through body very well(hematocrit 27); enlarged heart (upon radiological exam); constipation, and hypothermia. Plasma concentrations of total and free T4 and T3 follow:
Radioimmunoassay (RIA) of peripheral blood indicated elevated TSH levels. A TSH stimulation test did not increase the output of thyroid hormones from the thyroid gland.
a. What endocrine organ is involved here?
b. Is this a primary or secondary disorder? Why? (Is a TSH or TRH determination necessary for your diagnosis?)
c. Describe the feedback loop involved, indicating if there is an increased or decreased TSH level.
d. List several defects that could cause these symptoms.
e. Would you expect to find a palpable goiter? Explain your answer.
f. Describe a suitable treatment for this individual.
Answer:
1. Thyroid gland is the endocrine gland that is involved here.
2. TSH stimulation test did not show an increase in the output of thyroid hormones secreted from thyroid glands which makes it a primary disorder. The determination of TSH or TRH gives an idea about hypothyroidism if it is due to feedback inhibition of the pituitary or absence of TSH hormone from the pituitary, however, Circulating levels of TRH not necessary.
3. The feedback loop involves the following:
TRH hormone secreted from the hypothalamus triggers the anterior pituitary to secret TSH that in turn triggers the relapsing of the T3 and T4 levels by the thyroid glands. If there is a low level of T3 and T4 hormones then negative feedback takes place and increases the TSH output.
4. symptoms:
Not able to uptake the iodide into the cells of the thyroid gland
Defects in the conversion of iodide to iodine
tyrosine molecule iodization
secretion of the hormones from the Tg molecules
Less TSH receptors on the gland.
5. The chronic TSH stimulation due to negative feedback may cause hypertrophy of the gland, results in goiter formation.
6. synthetic hormone therapy is known as Synthroid such asT4 (L-thyroxine).

Deadly gas. Carbon monoxide is a colorless, odorless gas that binds to hemoglobin at an oxygen-binding site. Indeed, it binds 200 times as tightly as oxygen, accounting for its toxic nature. Even if only one of the four oxygen-binding sites on hemoglobin is occupied by carbon monoxide and the remaining three are bound to oxygen, oxygen is not released. Explain.
Answer:
The binding of carbon monoxide (CO) with hemoglobin leads to an R state even in conditions that should produce the release of oxygen. In consequence, CO-hemoglobin binding shifts the oxygen dissociation curve to the left.
Explanation:
Hemoglobin is a globular protein containing four heme groups that can bind to one oxygen each. This protein (hemoglobin) has two conformational states: the T-state, also known as deoxyhemoglobin (a tense state, where lacks O species), and the R-state, also known as oxyhemoglobin (a relaxed, fully oxygenated state). When carbon monoxide binds to hemoglobin, the protein can not release oxygen, shifting the oxygen dissociation curve -which expresses the percentage of oxygen saturation against the partial pressure of oxygen- to the left. Therefore, under CO-hemoglobin binding, the oxygen level in the tissues is reduced.

a. Blood glucose decreases to normal.
b. Blood glucose increases to normal.
c. Liver breaks down glycogen and releases glucose to the blood.
d. Liver takes up glucose and stores it as glycogen.
e. Pancreas releases glucagon.
f. Body cells take up more glucose.
Answer:
c. Liver breaks down glycogen and releases glucose to the blood.
Explanation:
Living system can be defined as the internal systems found in living organisms and how various materials are circulated inside organisms.
Generally, these living systems are self-organized life forms and are known to be very much interactive with their surroundings or environment. Also, living systems are dependent on the flow of information, matter and energy at various levels.
Some examples of living systems in organisms are respiratory system, nervous system, digestive system, and circulatory system.
Additionally, living systems comprises of the following components; cells, organs, muscle, tissues, blood, etc.
Organs can be defined as specialized body tissues united to perform specific functions in living organisms. Some examples of organs found in humans are brain, bladder, kidney, heart, intestine, eyes, lungs, liver, etc.
A liver refers to a large, essential organ that is reddish-brown in color which is used to synthesize proteins, secrete bile, and the detoxification of metabolites.
Glycogenolysis can be defined as a process which typically involves the breaking down of the primary carbohydrates (glycogen) present in liver into glucose so as to maintain blood glucose rates and provide necessary energy for living organisms.
Hence, the true statement is that liver breaks down glycogen and releases glucose to the blood.
In grammatically correct sentences trace the path of the products of photosynthesis as they exit the leaf.
Answer:
The correct answer is -
O2 - through the stomata
Glucose - through the phloem in the veins
H2O- through stomata
Explanation:
In the process of photosynthesis, plants capture light energy to initiate a chemical reaction that uses CO2 and H2O as reactants and converted them into oxygen and sugar or glucose as products. Thus, oxygen and glucose are the products form in photosynthesis.
These products are carried through various paths to the new location to get utilized. Glucose is carried by the phloem in the veins out to the plant whereas oxygen and water diffuse into the environment through stomata.
