A man who carries an allele of an X-linked gene will pass it on to
Explanation:
A man passes on his Y chromosome to all of his sons and his X chromosome to all of his daughters. Therefore, the sons of a man with an X-linked dominant disorder will not be affected, but all of his daughters will inherit the condition. A woman passes on one or the other of her X chromosomes to each child.
Describe Darwin's theory of evolution.
I need answers only in points for my lil sis, otherwise i'll report it..I'll reward brainliest to correct answer.
Answer:
Darwin's theory of evolution state that"all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual's ability to compete, survive, and reproduce".
Answer:
Charles Darwin's theory of evolution states that evolution happens by natural selection. Individuals in a species show variation in physical characteristics. Individuals that are poorly adapted to their environment are less likely to survive and reproduce.The barred owl has been moving into the habitat of the spotted owl. This could lead to a reduction in the spotted owl population if what?
Answer: If there is competition for food and nesting areas.
Explanation: Barred owls and spotted owls are well known as rivals. Barred owls are known to be aggressive towards spotted owls and are both bigger and more aggressive than them.

What is NOT a function of the reticular formation?
a. sleep b. breathing c. memory d. pain transmission
Answer:
c. memory
Explanation:
Memory is not a function of the reticular formation. Sleeping, breathing, and pain transmission all are the functions of reticular formation. Thus, the correct option is C.
What is reticular formation?
Reticular formation is a part of the pons region of brain which controls the sleep-wake cycle and also filters stimuli to separate out relevant background stimuli from irrelevant ones.
Reticular formation is one of the phylogenetically earliest parts of the brain and it is crucial for controlling some fundamental processes such as sleeping, breathing, and pain transmission.
The reticular formation is an essential process for the numerous activities of the brainstem. It is located strategically amid the significant nuclei in the brain cells and the nerve fibers that traverse it. The reticular formation looks like an intricate web network.
Therefore, the correct option is C.

why is a dominant acele called dominant
Answer:
Dominance is a relationship between two alleles of a gene and their associated phenotypes.
A "dominant" allele is dominant to a particular allele of the same gene that can be inferred from the context, but it may be recessive to a third allele, and codominant (both appear in the organism) to a fourth.

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.
Chickens that carry both the alleles for rose comb (R) and pea comb (P) have walnut combs, whereas chickens that lack both of these alleles (that is, rr pp) have single combs. From the information about interactions between these two genes, determine the phenotypes and proportions expected from the following crosses:
a. RR Pp × rr Pp;
b. rr PP × Rr Pp;
c. Rr Pp × Rr pp;
d. Rr pp × rr pp

There are two diallelic genes that code for chickens combDominant alleles R and P express rose comb and pea comb, respectivelyWhen they are together in a genotype, they express walnut combs, R-P-Recessive alleles are r and pGenotypes with only recessive alleles express single combs, rrppSo, genotypes and phenotypes would be like

How are traits inherited by offsring?
Answer:
Traits are passed to offspring by the offspring parents.
Explanation:
the genes that control a trait come in pairs, one from each parent. If a gene pair contains a dominant allele (a variation of genes that will produce phenotype,) than the offspring gains that trait from the dominant parent.
why does competition happen?
Answer: D
Explanation: Competition is a negative interaction that occurs among organisms whenever two or more organisms require the same limited resource. All organisms require resources to grow, reproduce, and survive. ... Therefore, competitors reduce each other's growth, reproduction, or survival.

Flower diameter in sunflowers is a quantitative trait. A plant with 6-cm flowers, from a highly inbred strain, is crossed to a plant with 30-cm flowers, also from a highly inbred strain. The F1 have 18-cm flowers. F1 × F1 crosses yield F2 plants with flowers ranging from 6 to 30 cm in diameter, in approximately 4-cm intervals (6, 10, 14, 18, 22, 26, 30). An 18-cm F1 plant is crossed to a 6-cm plant. What is the probability of an offspring with one additive allele, if all genes that influence this trait are unlinked?a. 1/3b. 1/4c. 1/6d. 3/8e. 1/16

The chart below shows the inferred evolution of some dinosaurs during three time periods in Earth’s history.
Which dinosaur most likely evolved from Coelophysis?Immersive Reader
(5 Points)
Camptosaurus
Triceratops
Theodont
Tyrannosaurus
Answer:
camptosaurus
Explanation:
I think it's correct
The Dinosaur that most likely evolved from Coelophysis is known as Camptosaurus. Thus, the correct option for this question is A.
What is Evolution?Evolution may be characterized as the complete methodology of gradual change that takes place over many generations, during which species of animals, plants, or insects slowly change some of their physical characteristics.
Coelophysis lived during the late Triassic period some 216.5 to 203.6 million years ago. Researchers believe that this small theropod lived on river floodplains where it walked alongside crocodilian-like Camptosaurus. They were small theropod dinosaurs that lived in what is now North America and Southern Africa during the late Triassic.
Therefore, the Dinosaur that most likely evolved from Coelophysis is known as Camptosaurus. Thus, the correct option for this question is A.
