Examine the following crosses carried out to explore inheritance of traits in pea
plants
Parent cross: rough, soft peas X smooth, hard peas F1: all rough, hard Test
cross: rough, hard X smooth, soft peas F2: 115 rough soft, 110 smooth hard, 8
rough hard, 12 smooth soft
Identify which traits are dominant, and either support or refute the hypothesis
that the traits rough/smooth and soft/hard assort independently according to
Mendel's law,
Answer:
rough (RR or Rr) and hard (HH or Hh), are the dominant traits. smooth (rr) and soft (hh), are the recessive traitsWe reject the hypothesis because genes are linked, so they do not assort independently.

69 points! Pls tell me where to put the star I will mark brainliest but If ur answer is unrelated I will report u. Place the STAR on the pioneer species.
Answer:
I believe it is the moss on the ground because moss can grow quickly and since a pioneer species is the first thing that came, it colonized first, like a pioneer. Have a nice day :)
Explanation:
What characteristic could provide a species with a better chance of surviving a drastic environmental change?
(A) A small population size
(B) A highly diversified gene pool
(C) specialized cells within the body
(D) Many individuals with the recessive trait
A highly diversified gene pool could provide a species with a better chance of surviving a drastic environmental change. So, the correct option is B.
What is Diversified Gene pool?Greater genetic diversity within a population is made possible by a diverse gene pool, which raises the possibility that at least some members of the population will exhibit features that are more adapted to the new environment.
This variety can develop as a result of gene flow from other populations or mutations. The number of people having the recessive trait or a limited population size, however, would not always give an advantage in enduring environmental change. A species may have a better chance of surviving a severe environmental shift if its gene pool is extremely varied.
Therefore, the correct option is B.

How does the long-term overuse of antibiotics lead to pathogen resistance???
hope this helps you
have a nice day:)
Anytime antibiotics are used, they can contribute to antibiotic resistance. This is because increases in antibiotic resistance are driven by a combination of germs exposed to antibiotics, and the spread of those germs and their mechanisms of resistance.
The hormones of the adrenal medulla are modified
(a) fatty acids. (b) amino acids. (c) monosaccharides. (d) nucleotides. (e) steroids.
Answer:
b
Explanation:
hormones of adrenal medulla are Adrenaline and non- Adrenaline. they are the derivatives of amino acids called Tyrosine( aromatic Amino acid)
The hormones of the adrenal medulla are modified versions of amino acids. Thus, the correct option is B.
What is the Adrenal medulla?The adrenal medulla may be defined as an internal part or region of the adrenal gland which is located at the region of the top of each kidney.
The adrenal gland is a small gland that comprises the adrenal cortex and adrenal medulla. The adrenal cortex synthesizes steroids hormones like mineralocorticoids, glucocorticoids, etc. While the adrenal medulla is responsible for the secretion of epinephrine and norepinephrine.
The hormone epinephrine is also known as adrenaline. It is often called catecholamine. This epinephrine is extracted from the derivatives of amino acids known as tyrosine.
Therefore, the hormones of the adrenal medulla are modified versions of amino acids. Thus, the correct option is B.

functional group of Acetaldehyde
Answer:
―CHO
Explanation:
Organic compounds are compounds that contain carbon-hydrogen bonding in their structural formula, hence, virtually all organic compounds are referred to as HYDROCARBONS. Organic compounds consists of a wide variety of groups, which are individually identified by their FUNCTIONAL GROUP.
The functional group of an organic compound is responsible for its chemical behavior irrespective of other atoms in its structure. According to this question, ALDEHYDE GROUP is an organic compound also called ALKANAL. It has the functional group as follows:
R - C - H - O
Where R is a side chain
- The second member of the aldehyde group is called ACETALDEHYDE with the chemical formula; CH3CHO. Since it is a member of the aldehyde group, its functional group is -CHO.

The first unstable compound formed during C3 cycle is:
(a) 3-carboxy,2-keto, 1,6 bi phosphorobitol
(c) 2-carboxy,3-keto,1,5 biphosphorobitol
(b) 2-carboxy,3-keto,1,5-biphosphorobitol
(d) 3-carboxy,3-keto, 1,6-biphosphorobitol
Answer:
(b) 2-carboxy,3-keto,1,5-biphosphorobitol
Explanation:
2-carboxy, 3-keto, 1,5-biphosphorobitol is the first unstable molecule formed during the C3 cycle. Due to its instability, this molecule is quickly broken down into two molecules each containing 3 carbon atoms, called 3-phosphoglyceric acid, this breakdown is done through water in a process known as hydrolysis.

what are the chances that a color blind man will have a color blind grandson what are the genotypes for all involved.
Answer:
Depends
Explanation:
It depends if the genotypes are hetero.zygous or resessive/dominant homo.zygous. Being colorblind could be represented by a resessive genotype like, bb. if their son/daughter has Bb or bb or their son/daughter in law has a resessive trait then having a color blind grandchild maybe possible. The colorblind grandson has parents that both have at least 1 resessive trait, then the grandson could not be colorblind.
