what type of pollination happens when pollen grains from anther are transferred to the stigma of a flower what belongs to the same plant?
A.across-pollination
B.auto-pollination
C.cross-pollination
D.self-pollination
Answer:
It is D
Explanation:
Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. Cross-pollination is the transfer of pollen from the anther of one flower to the stigma of another flower on a different individual of the same species.
A. If 15 ml of a liquid has a mass of 11.85 grams,
(1) What is the density?
(2) What is the liquid?
Answer:
1. 0.79g/mL
2. Ethanol
Explanation:
The density of a substance can be calculated by using the formula;
Density (g/mL) = mass (g) ÷ volume (mL)
According to the information provided in the question, mass = 11.85grams, volume = 15mL.
Hence, density = 11.85g ÷ 15mL
= 0.79
Density of the liquid = 0.79g/mL.
Substances usually have their own unique density, which is one of the properties that distinguish them. In this case, ETHANOL is the liquid that possesses a density of 0.79g/mL.

Two women gave birth in the same hospital on the same afternoon. Their babies were taken
away, and then brought back to them one hour later. One of the women was worried that
she had been given the wrong baby. She asked for blood tests to be carried out. The hospital
found that she was group A and her husband was group O. The other mother was group
AB and her husband was group A. The woman with blood group A had been given the baby
with blood group O. The woman with group AB was given the baby with blood group B. Use
genetic diagrams to determine whether the women had been given the right babies.
Answer:
Explanation:
If the Husband of Woman One had group O blood, than It would be hard for Woman 2's baby to have group O blood, because the Parents of Baby 2 are AB and A. So the hospital did give the woman the right babies
Answer:
They were given the right baby cause the women who was worried her husband was group o and the baby they got was group o and the other women had a child with group b and her blood was a and b so yes it’s correct

Which pattern of inheritance does nose size follow?
complete dominance
codominance
incomplete dominance
sex-linked dominance
Answer:
incomplete dominance
Explanation:
This is because incomplete dorminance is a type of inheritance pattern in which a dorminant allele does not completely masked the effect of recessive allele. The recessive allele is expressed little and the dorminant. Example is the nose size. The allele for big nose and recessive allele for small nose are not completely dorminant.
A. GGU UAU
B. CCT TAC
C. ACC ATA
D. UGG UAC
According to Sandra Scarr's description of the three ways that heredity and environment can be correlated, passive genotype-environment correlations occur because Multiple Choice children seek out environments that are stimulating. biological parents provide a rearing environment for a child. a child's genetically influenced characteristics elicit certain types of environments. certain genes evoke environmental support.
Answer:biological parents provide a rearing environment for a child
Explanation:
According to Sandra Scarr's description on the correlation that exist between heredity and the environment, passive genotype-environment correlations occur due to the fact that certain genes evoke environmental support.
It should be noted that passive genotype-environment correlation takes place due to the fact that there's passive inheritance on the genes of the children and the environment which are provided by their parents.An example of such characteristics is when the child is athletically inclined as it's possible for the family to be athletes.In conclusion, the correct option is D.

How are astronomers able to determine what elements are found in other stars and galaxies?
Answer:
This type of study is called spectroscopy. The science of spectroscopy is quite sophisticated. From spectral lines astronomers can determine not only the element, but the temperature and density of that element in the star. The spectral line also can tell us about any magnetic field of the star.

The bananas eaten today are not the bananas that have always been eaten. In the early 1900's a different banana called the "Gros Michel" or "Big Mike' was the primary banana sported By 1950 a fungus had wiped outalmost all of the banana plantations that used the Big Mike and crops had to be changed. Bananas that are available throughout stores worldwide are all clones of the Cavendish banana Cloning is a process where the DNAfrom one organism is identically replicated and used to create a genetically identical organism Some plantations are starting to report a fungus impacting their Cavendish crops the same way the Big Mike crops wereImpacted.

Hydrogen bonding is primarily responsible for the high ______ of water.
a. freezing point
b. boiling point
c. conductivity
d. polarity
The hydrogen bond is responsible for many of the anomalous physical and chemical properties of compounds of N, O, and F. In particular, intermolecular hydrogen bonding is responsible for the high boiling point of water (100 °C) compared to the other group 16 hydrides that have much weakerhydrogen bonds
Explanation:
Therefore, option b is correct.Hydrogen bonding is primarily responsible for the high boiling point of the water. Thus, the correct option is B.
What is Hydrogen bonding?Hydrogen bonding is an interaction which involves a hydrogen atom that is located between a pair of other atoms such as nitrogen, oxygen, and fluorine which have a high affinity for electrons, and such a bond is weaker than an ionic bond or a covalent bond but are stronger than van der Waals forces and dispersion forces.
Hydrogen bonding is primarily responsible for the high boiling point of water solvent. Hydrogen bonding is a strong affinity. Hydrogen bonding is created when a hydrogen atom is bonded to an electronegative atom by approaching a nearby electronegative atom.
Therefore, the correct option is B.

Phenotype of offspring:—-?
Genotypes of offspring:—-?
Lol I need help
Answer:
The correct answer is -
The phenotype of offspring (first cross or F1): 100% tall
The genotype of offspring (first cross or F1 - 100% Tt or heterozygous)
The phenotype of offspring in F2 (F1 × F1) - 3:1 (3 tall: 1 dwarf)
The genotype of offspring in F2 (F1 × F1) - 1:2:1 (One dominant tall: two heterozygous tall: one dwarf)
Explanation:
In this experiment of Mendel, Mendel selected the pea plant as it has various characters, short life span, and easy to breed. For this, he used two true breed lines, tall plants that had dominant allele TT and dwarf plant tt (recessive). In presence of the dominant allele, recessive alleles do not show their characteristics and only express if both alleles are recessive.
In the first cross of TT and tt
Gametes: T and t
offspring: Tt
the offsprings are all tall and heterozygous which means one dominant and one recessive allele.
second cross or F1 × F1
Tt × Tt
gametes: T, t and T, t
offspring: TT, Tt, Tt, tt
Thus,
The phenotype of offspring (first cross or F1): 100% tall
The genotype of offspring (first cross or F1 - 100% Tt or heterozygous)
The phenotype of offspring in F2 (F1 × F1) - 3:1 (3 tall: 1 dwarf)
The genotype of offspring in F2 (F1 × F1) - 1:2:1 (One dominant tall: two heterozygous tall: one dwarf)

Explain the existing problems of Agroforestry market in Pakistan
Answer:
Forest ecosystems in Pakistan are no exception and the country faces a crisis as its growing population ([ 208 million) places increasing pressure on the country's food production systems and forest resources. Effective food systems that enhance productivity, increase economic outputs, improve ecological outcomes and maintain social acceptance are needed. Agroforestry, a traditional land management system in Pakistan, offers the opportunity to meet these goals. Planting trees on private farmland provides clear ownership of any timber resource and well managed systems have great potential both to boost agriculture and reduce wood shortages.
Which of the following increases the population size?
a. favorable light and temperatures
b. inadequate food supply
c. inability to complete
d. inability to migrate, hide or defend

Favorable light and temperatures can increase population size
Inadequate food supplies can lead to starvation and/or death
If a population can’t migrate, hide or defend, they will likely die
Populations need to be able to resist disease or they will be wiped out
