What is the purpose of xylem?
Answer:
xylem, plant vascular tissue that conveys water and dissolved minerals from the roots to the rest of the plant and also provides physical support. Xylem tissue consists of a variety of specialized, water-conducting cells known as treachery elements. The vascular system is comprised of two main types of tissue: the xylem and the phloem. The xylem distributes water and dissolved minerals upward through the plant, from the roots to the leaves. The phloem carries food downward from the leaves to the roots.

A congenital cataract is a clouding of the lens of the eye that is present from birth. The mode of
inheritance for one type of congenital cataract is from a dominant allele. Suppose a man is
heterozygous for this type of congenital cataract, and a woman does not have cataracts. If these two
individuals have a child, what is the probability that the child will have this type of congenital cataract?
a. 25%
b. 50%
c. 75%
d. 100%

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.
What does this quote mean to you?
Quote: “Everybody is a genius. But if you judge a fish by its ability to climb a tree, it will live its whole life believing that it is $tupid.”-Albert
Answer:
It basically means that everyone is a genius in their own way and everyone has their own skills. If you decide to judge someone on what they cannot do (eg. a fish climbing a tree) rather than what they can do, it's gonna make the person feel $tupid their entire life. Not everyone can do the same thing and not everyone has the same abilities. A fish may not be able to climb a tree, but it can swim well. Just like a bee wouldn't be able to swim, but it can fly.

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)

Phenotype
Answer:
The term "phenotype" refers to the observable physical properties of an organism; these include the organism's appearance, development, and behavior. An organism's phenotype is determined by its genotype, which is the set of genes the organism carries, as well as by environmental influences upon these genes.

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.

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.

2. Which type of nuclear energy is used in commercial nuclear reactors to produce electrical
energy? In two to three sentences, describe how a nuclear power plant works.
Answer:
nuclear fission
Nuclear power comes from nuclear fission
The steam is used to spin large turbines that generate electricity. Nuclear power plants use heat produced during nuclear fission to heat water. In nuclear fission, atoms are split apart to form smaller atoms, releasing energy
In nuclear power plants, neutrons collide with uranium atoms, splitting them. In the core of nuclear reactors, the fission of uranium atoms releases energy that heats water to about 520 degrees Farenheit. This hot water is then used to spin turbines that are connected to generators, producing electricity
