Q. How is the sex of the child determined in human beings ?
Please answer dis also..thanks!​

Answers

➜ In human beings, sex of the child depends upon which kind of male gamete fertilise the female gamete. If sperm carrying X chromosome fertilises the ovum carrying X chromosome, then the child born will be a girl. If a sperm carrying Y chromosome fertilises the ovum which carries X chromosome, then the child born will be a boy.

Hox Genes:

A cow born in Russia has two tails. Which of the following most likely was the cause of this abnormality?

Answers

Domestication and selective breeding has resulted in over 1000 extant cattle breeds. Many of these breeds do not excel in important traits but are adapted to local environments. These adaptations are a valuable source of genetic material for efforts to improve commercial breeds. As a step toward this goal we identified candidate regions to be under selection in genomes of nine Russian native cattle breeds adapted to survive in harsh climates. After comparing our data to other breeds of European and Asian origins we found known and novel candidate genes that could potentially be related to domestication, economically important traits and environmental adaptations in cattle.

process by which organisms with favorable variations survive and produce more offspring than well-adapted organisms

A. evolution
B. Natural Selection
C. Speciation

Answers

Answer:

B. Natural Selection

Explanation:

Any animal with the favorable qualities to survive is naturally able to produce more offspring than others. This is theory was first theorized by Charles Darwin with his Finch birds.

Which of the following is not one of Mendel's Laws?
a) Law of Conservation of Mass
b) Law of Segregation
c) Law of Dominance
d) Law of Independent Assortment

Answers

Answer:

A

Explanation:

Law of conservation of mass was discovered by Lavoisier

Law of Conservation of Mass is not one of Mendel's Laws. Therefore, the correct option is A.

What are Mendel's Laws?

Gregor Mendel's research with pea plants in the 19th century led him to reveal three fundamental laws of inheritance, known as Mendel's laws. There are three laws:

1. Law of Segregation: Each individual has two alleles for each trait, and this law indicates that these alleles separate (separate) during the development of gametes, or reproductive cells. This indicates that only one allele per trait is present in each gamete.

2. According to the law of independent assortment, the inheritance of one trait is independent of the inheritance of another. In other words, the segregation of alleles for one trait is independent of the segregation of alleles for the other trait.

3. The law of dominance states that when two different alleles are present in an individual, the dominant allele will dominate the recessive allele in terms of expression. Only when both alleles are recessive will the recessive allele be expressed.

Therefore, the correct option is A.

The correct options are;

Mammals and turtles are more closely related than are lungfishes and sharks.

Descendants of organism (d) have legs.

Rays and frogs have a vertebral column.

-Birds and ray-finned fishes have a notochord and jaws

Answers

Answer:

The size of the bag will shrink due to movement of water molecules out of the bag into the beakerdue to osmosis.

Explanation:

The difference in concentration between two regions results in a phenomenon known as diffusion.

Diffusionnis the process by which molecules of a substance move from regions of higher concentration to regions of lower concentration until equilibrium concentration is reached by the two regions. Water molecules moves across regions of different concentration through a semipermeable membrane in a special form of diffusion known as osmosis.

Osmosis refers to the movement of water molecules from regions of high concentration (dilute solutions ) to regions of low concentration (concentrated solutions ) through a semipermeable membrane until equilibrium is attained.

The solution in the bag is less concentrated than the solution innthe beaker. The bag serves as a semipermeable membrane allowing water molecules to move out of it into the beaker due to the difference in concentration of the two solutions. As a result, the size of the bag shrinks while the level of the solution in the beaker rises as it becomes less concentrated.

What is NOT a function of the reticular formation?
a. sleep b. breathing c. memory d. pain transmission

Answers

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.
