Kangaroos are mammals that lack a placenta. Therefore, they must have an alternate way of supplying the developing embryo with
Answer: yolk sac
explanation:
the placenta does not develop for a long time so the alternate way of supplying the developing embryo is through the yolk sac which the embryo can receive nutrients and respiratory gas exchange through which the placenta will be formed later.
Kangaroos are mammals that lack a placenta; therefore, they must have an alternate way of supplying the developing embryo with nutrients, as these should be passed from the mother to the embryo during the time of pregnancy.
What is the function of the placenta in pregnancy?The placenta is an organ that develops during pregnancy to provide nourishment to the growing fetus and to remove waste products from the baby's blood and is attached to the wall of the uterus and connected to the baby by the umbilical cord, it is responsible for producing hormones that maintain the pregnancy, such as progesterone, which helps to keep the lining of the uterus thick, also produces human placental lactogen, which helps stimulate the mother's mammary glands to produce milk.
Hence, kangaroos are mammals that lack a placenta; therefore, they must have an alternate way of supplying the developing embryo with nutrients, as these should be passed from the mother to the embryo during the time of pregnancy.

Why do elderly persons often develop bowed back and appear to lose height?
Answer:
When we get older, we experience a loss of bone density and our bones begin to thin and become weaker, which results in osteoporosis, causing us to develop bowed backs and appear to lose height.
We lose bone density as we age, and our bones start to thin and weaken. This leads to osteoporosis, which makes us appear smaller and causes us to acquire bowed backs.
What is osteoporosis ?Osteoarthritis is an osseous disease that arises when the body makes either too little bone or loses too much bone. Like a result, bones deteriorate and are more prone to breaking from a trip or, in extreme circumstances, from tiny bumps or sneezes. Under a magnification, healthy bone resembles a honeycomb; the term "osteoporosis" refers to porous bone.
What is treatment of osteoporosis?Typically, bisphosphonates are used initially for treating osteoporosis. Among these is the when first tablet Alendronate (Fosamax). Weekly or monthly pills of was also (Actonel). Ibandronate (Boniva), a tablet taken every month or an IV infusion given every 3 years. The most accurate test for identifying osteoporosis and determining the risk of fracture is commonly believed to be bone density testing by DXA now at hip and spine. Some persons get peripheral DXAs, which assess the thumb and heel bone densities.

Which of the following areas is located in the frontal lobe of the brain?
Broca's area
O hippocampus
thalamus
Wernicke's area
Answer:
Brocas area
Explanation:
Broca's area is located in the frontal lobe of the brain.
The brain region known as Broca's area is located in the left frontal lobe and is considered the nucleus that controls expressive language.
Thus, in both writing and speech, this portion of the central nervous system specializes in the production of a message with internal coherence and articulated through the language fractions.
In this area, specifically, there are capacities such as:
• Order the phonemes when making a word.
• The organization of words within a sentence.
• The semantic integration of the content to be expressed.
• Motor planning necessary for the expression of language.
Therefore, we can conclude that Broca's area located in the third gyrus in the frontal lobe is responsible for the articulation of language in any of its forms.

Can someone please help me I am doing a project were I have to wet a cloth and wrap it around a thermometer. Then I have a dry cloth and wrap it around another thermometer. The degrees for the wet one was 40 degrees and the dry one was 35. I had to do it three times and the dry one was still 35 on three trys and the wet one was still 40. now calculate the average. (f degrees - 32) x 5/9= the celsius
Answer:
Explanation:
35 + 35 + 35 + 40 + 40 + 40
(the numbers are there three times due to each trial value. you have to account for each.)
From the math you get 225.
Divide 225 by six due to their being six values
37.5 would be the average without the (f degrees-32) x 5/9
(now following the formula you put ((dont know if you have to follow though)))
37.5 - 32 x 5/9 = 3.055555556 degrees celcius.
What would be the mRNA base sequence formed from ACC CTG GTA GCT
Answer:
Explanation:
DNA utilizes four bases, adenine (A), guanine (G), cytosine (C), and thymine (T), in its code. RNA also uses four bases. However, instead of using 'T' as DNA does, it uses uracil (U). Therefore, if your DNA sequence is 3' T C G T T C A G T 5', the mRNA sequence would be 5' A G C A A G U C A 3'.
Which question would be asked in a dichotomous key?
A. How long are the insect's antennae?
B. Are the insect's antennae longer than its head?
C. Are the insect's antennae long or short?
D. How does the insect use its antennae?
Answer:
B. Are the insect’s antennae longer than its head?
Explanation:
Dichotomous key refers to the tool or method which helps the scientist to identify organisms.
It uses a specific series of questions which help in segregation of organisms and ultimately help the scientist to identify the organism on the basis of the observations or properties share by the organism.
Example of a simple dichotomous key is shown below.
Similarly, insects can have antennae longer or shorter than their heads. Thus, the question "Are the insect’s antennae longer than its head?" would help in segregating insects based on their antennae length.
happy to help ya:)
The statement B is correct. Are the insect’s antennae longer than its head?
What do you mean by dichotomous keys?A dichotomous key is an important scientific tool, used to identify different organisms, based the organism's observable traits. Dichotomous keys consist of a series of statements with two choices in each step that will lead users to the correct identification.
Moreover, for example, in tree identification, a dichotomous key might ask whether the tree has leaves or needles. The key then directs the user down one list of questions if the tree has leaves, and a different question list if it has needles.
Therefore, dichotomous keys are useful for biological classification as well as identification. The word dichotomous is derived from the Greek words meaning “two parts.” Each step in the key provides two contrasting choices about a characteristic.

Which is NOT a role played by a type of RNA in protein synthesis?
O mRNA transcribes the DNA template.
rRNA makes up ribosomes, which translate the genetic code into a protein.
O tRNA pairs RNA bases with amino acids.
O pRNA is the product of chemically linked amino acids.
Answer:
pRNA is the product of chemically linked amino acids.
Explanation:
All the other choices are exactly the roles of RNA in protein synthesis: mRNA "messenger" RNA transcribes the DNA and travels out of the nucleus; then rRNA "ribosomal" RNA in the ribosome helps assemble the protein using the mRNA; tRNA "transfer" RNA brings amino acids to the assembly line of ribosome and mRNA.
There is no pRNA that I know of, although there are many types of other RNAs like piRNAs (piwi RNAs!) or siRNAs.
What do prokaryotes have in common with eukaryotes?
A. They both have a Golgi apparatus.
B. They both have mitochondria.
C. They both have a nuclear membrane.
D. They both have a liquid cytoplasm.
Answer:
They both have a liquid cytoplasm.
Explanation:
A liquid cytoplasm is an essential part of a cell, in both prokaryotes and eukaryotes. It supports the internal components of the cell, and is the site of many vital cellular processes, such as glycolysis (the first part of cellular respiration).
The Golgi apparatus and the mitochondria are membrane-bound organelles that serve a specific purpose in eukaryotic cells. However, prokaryotic cells do not contain any membrane-bound organelles.
Prokaryotes do have a nucleus, like eukaryotes, but unlike in a eukaryotic cell, a prokaryotic nucleus is not surrounded by a nuclear membrane. Instead, it is just confined to a certain area of the cell, called a nucleoid.
Prokaryotes and eukaryotes both have a nuclear membrane. Option C
What is the commonality?
Prokaryotes and eukaryotes are two large categories of cells with notable variations in their organization and structure. They do, however, have some things in common.
The existence of a nuclear membrane or nuclear envelope is one of the similarities between prokaryotes (such as bacteria) and eukaryotes (such as plants, animals, fungi, and protists). The cell's genetic material, which can be either DNA or RNA, is encased in the nuclear membrane. It divides the cellular components into the nucleus and the remainder.

Rabbits can be best described as primary consumers. The correct option is b.
What are primary consumers?The 2nd trophic level is comprised of primary consumers. They are also known as herbivores. They just feed primary producers, including such plants or algae. A grasshopper, for example, is a primary consumer in the Everglades.
Primary consumers are rabbits because they are the first step up from autotrophs. Autotrophs, such as grass, are eaten by primary consumers such as rabbits.
The animals that eat the primary consumers are known as secondary consumers.
Herbivores are the primary consumers of plants. Primary consumers include caterpillars, insects, grasshoppers, termites, and hummingbirds, which only eat autotrophs (plants).
Rabbits are herbivores because they only eat plants - and herbivores are consumers because they eat plants to survive. Consumers include deer, grasshoppers, and rabbits.
