Answers

Answer 1

Answer: One of two principles of heredity, first formulated by Gregor Mendel,founded on his experiments with pea plants and stating that the members of a pair of homologous chromosomes segregate during meiosis and are distributed to different gametes. Also called law of segregation, principle of segregation.

In which structure of the female reproductive system is a zygote typically found? A. Fallopian tube
B. Uterine wall
C. Uterus
D. Ovary

i think it is A but im not sure

Answers

Zygote is formed in the Fallopian tube.

Once in a month the egg is released from the ovary to the fallopian tube where the sperm of male is present for the process of fertilization which results in formation of zygote. Zygote remains in the fallopian tube for the next three to four days. Then it travels to the uterus for the implantation where the growth and nourishment of embryo takes place.

It's A. Fallopian Tube. The ovaries create the egg and the fallopian tubes hold the zygote until it is fertilized, then transfer it to the uterus.

During nuclear fusion, when a hydrogen atom with 1 proton is fused with a nitrogen atom with 7 protons, the resulting atom is: A a carbon atom with 6 protons B a nitrogen atom with 7 protons C an oxygen atom with 8 protons D hydrogen and nitrogen can't combine during nuclear fusion Any help/explanation would help

Answers

Answer: The correct answer is Option C.

Explanation:

Nuclear fusion reaction is defined as the reaction in which two lighter nuclei join (fuses) together to form a heavier nuclei.

Number of protons determine the atomic number of an element.

The chemical reaction representing the nuclear fusion of nitrogen and hydrogen is given by the equation:

$_7\textrm{N}+_1\textrm{H}\rightarrow _8\textrm{O}$

The fusion of these two elements results in the formation of oxygen atom which has 8 protons.

Thus, the correct answer is Option C.

the answer is c because an oxygen atom with 8 protons witch as well also number of protons increase from 7 to 8.

Which of the following best explains how a biotic factor can control the population of a species in an ecosystem?A sudden drop in temperature may cause many individuals in a population to die.

Competition between two species may force one of them to migrate to survive.

Disease may lead to a decline in the reproductive rate of the species’ main predator.

Lack of water during a drought may cause many of the individuals in a population to die.

Answers

Answer:

The most appropriate answer would be Competition between two species may force one of them to migrate to survive.

Competition is a type of biological interaction in which organisms of same or different species compete for similar resources essential for their survival in an ecosystem.

Organisms can compete for limiting sources (such as air, water, food), territory, and mating rights.

In inter-species competition, species with the slightest advantage will grow and result in the migration or extinction of other species in that ecosystem.

Thus, the population of other species would decrease or extinct in that ecosystem.

For example, lion and cheetah may compete for their common prey that is, deer.

Answer:

B): Competition between two species may force one of them to migrate to survive.

Stella is stressed about her upcoming midterm exams. Which glands are managing that stress during the tests? reproductive and pancreas thyroid and parathyroids hypothalamus and pineal pituitary and adrenals

Answers

Pituitary and adrenalsglands manage the stress during the tests.

The adrenal glands are responsible for producing hormones that help regulate metabolism, blood pressure, stress response, and other essential functions.

For its part, the adrenal medulla, which is located within the adrenal cortex in the center of the gland, is responsible for secreting "stress hormones" such as adrenaline and norepinephrine.

The adrenal glands are an intricate part of the hypothalamic-pituitary-adrenal axis is composed of:

Hypothalamus, which is a nervous structure located at the base of the brain that acts as a link between the endocrine system and the nervous system.

Pituitary gland, also located at the base of the brain,that causes the secretion of the adenocorticotropic hormone.

Adrenal glands, which are located on the upper pole of each of the kidneys and are composed of the cortex and the medulla, which gives rise to the production of corticosteroids that pass into the circulatory stream.

Before the appearance of a danger or stressor, the hypophysi-adrenal axis is activated; there is an instantaneous and automatic reaction that is made up of a series of symptoms that are always the same, although from greater to lesser intensity.

Then the body tries to overcome, adapt or face the presence of stressor that it perceives as a threat, normalizing the levels of corticosteroids.

Therefore, we can conclude that pituitary and adrenals glands manage the stress during the tests.

Answer:

d. pituitary and adrenals

Explanation:

The adrenal glands are two glands that sit on top of your kidneys that are made up of two distinct parts. The adrenal cortex—the outer part of the gland—produces hormones that are vital to life, such as cortisol (which helps regulate metabolism and helps your body respond to stress) and aldosterone (which helps control blood pressure).

The pituitary gland is sometimes referred to as the thermostat because it controls the other hormone secreting glands in the body. It had the ability to monitor and send appropriate signals to regulate hormones. It controls functions such as thyroid activity, growth, urine production and the function of other organs in the body.
