Answer: Genes come in pairs which are passed down by the parents'. Both parents pass on one copy of their genes to create a gene for the child; this will later create a trait.

Answer: Addison disease is an adrenal insufficiency. This occurs because of the fact that adrenal gland produces very low quantity of hormones like cortisol, and aldosterone.

Explanation:

1. The symptoms of addison disease are loss of appetite, increased thirst, low mood, and muscle fatigue.

2. The addison disease is an autoimmune reaction, which can affect people of all age groups.

3. It can cause other diseases like tuberculosis.

4. The hormone replacement therapy is ideal for the treatment for addison disease. The use of oral corticosteroids is ideal. The diet containing balanced proteins, carbohydrates, fats, increased intake of vegetables including vitamins, and minerals are necessary for treatment of addison disease.

in a covalent bond, the atoms bond by sharing electrons. Covalent bonds usually occur between nonmetals. For example, in water (H2O) each hydrogen (H) and oxygen (O) share a pair of electrons to make a molecule of two hydrogen atoms single bonded to a single oxygen atom.

Answer:

An epidemiologist

Answer:

A g I need the same answer homie

Explanation:

Answer:

The answer is Anaphase I separates homologous chromosomes and anaphase II separates sister chromatids into daughter cells.

Meiosis is a cell division which results in the reduction of chromosome number by half - from diploid to haploid - in daughter cells. It consists of meiosis I and meiosis II. Meiosis I produces two haploid cells. Meiosis II is analogous to mitosis, so in total, meiosis results in four haploid cells. So, in meiosis, there are two anaphases - the anaphase I in meiosis I and the anaphase II in meiosis II.

In anaphase I, the sister chromatids separate from each other to the opposite sides of the cells. In meiosis I there are 46 chromosomes in duplicate, which are present as pairs of sister chromatids. In anaphase of meiosis II, since the cell is haploid, there are 23 chromosomes in duplicate, which are present as sister chromatids.

Answer: d) the baby is male

Explanation: Ovules contain X chromosomes whereas sperms come in two types: one type contains x chromosome and the other contains Y chromosome.

When a sperm containing X chromosome fertilises with an ova, the zygote will have two X chromosomes. This zygote would develop into a female child. When a sperm containing Y chromosome fertilises with an ova, the zygote will have one X and one Y chromosome. This zygote would develop into a male child.

Answer: the baby is male

Explanation: female babies are born with 2 X chromosomes. Haploid babies have a one set of unpaired chromosomes. It’s impossible for a baby to have an X and Y chromosome pair and be prokaryotic. Males have one X chromosome and one Y chromosome, so it has to be male.

Answer:

The options are

A. There will be less soil and dust in the air as construction increases.

B. The atmosphere will improve as more people move to large cities.

C. Making major changes to the atmosphere can be a costly process.

D. It is more important to protect land and water resources than the atmosphere.

The answer is C. Making major changes to the atmosphere can be a costly process.

Explanation:

Making major changes to the atmosphere to the atmosphere to help protect Earth's resources​ is costly because no one knows the effects of what the changes will have when effected. Another angle is effecting the changes will be a very expensive one as the atmosphere is very large and will be difficult having it happen.

This however validates making major changes to the atmosphere can be a costly process as the right option.

Answer:

I think it is plastic

Explanation:

even though it take 400 years for a paper bag to decompose, people use more plastic.

Answer:

Paper is better for environment

Explanation:

Paper is because it decomposes much more quickly than plastic, and because of that it is less likely to be a source of danger and  will not pose a risk to wildlife. Paper is also more recyclable, while plastic can take between 400 and 1,000 years to decompose.

Answer:

a plant cell has a rigid cell wall however an animal cell does not. (more info below)

Explanation:

Because a plant cells are surrounded by the rigid cell wall, it cannot use microfilaments to go through cytokinesis. Instead, it builds a cell plate in the middle of the cell to represent the division. An animal cell does not have this rigid structure, so it forms a cleavage furrow by pinching the cell in the middle with microfilaments. This will successfully divide the cell into two.

hooe this helped!

Answer:

Cytokinesis is the final stage of cell division in eukaryotes as well as prokaryotes.  In animal cells, the plasma membrane of the parent cell pinches inward along the cell's equator until two daughter cells form.  In plant cells, a cell plate forms along the equator of the parent cell.

Answer:

lipids (i think) :))

Explanation:

Answer:

The question is incomplete, the missing part i.e. the environmental change is:

(A) biomagnification

(B) acid rain

(C) eutrophication

The answers are:

1. Acid rain- Chemicals react with water and oxygen that enter water systems.

2. Eutrophication- Nutrients in excessive amounts enter water systems, causing algal bloom.

3. Biomagnification- A high concentration of toxic chemicals is present in the bodies of animals at the highest trophic levels

Explanation:

1. Acid rain is an environmental disorder in which rainfall becomes acidic due to pollution. The pollution is as a result of the release of gaseous chemicals e.g sulfur, nitrogen oxide, which are produced by industries, into the atmosphere. These chemicals then react with water in the atmosphere to form acidic solutions, which then falls back as rain. Hence, chemicals reacting with water and oxygen that enter water systems describes ACID RAIN.

2. Eutrophication is the pollution of water bodies with substances containing chemicals like nitrogen, phosphorus etc. The chemicals, which are in excess, serve as nutrients to algae, which uses them to grow excessively forming a bloom called ALGA BLOOM. Hence, nutrients in excessive amounts entering water systems, causing algal bloom describes EUTROPHICATION.

3. Biomagnification refers to the build up or accumulation of toxic chemical substances in the body systems of living organisms higher up in the food chain. Pollutants like pesticides, herbicides flow into water bodies and are absorbed by certain aquatic organisms. When these organisms are fed on by consumers, the harmful substances accumulates in their tissues until it reaches a maximum concentration. Hence, a high concentration of toxic chemicals present in the bodies of animals at the highest trophic levels describes BIOMAGNIFICATION.

Answer:

1. Acid rain- Chemicals react with water and oxygen that enter water systems.

Answer:

A sucessão primária ocorre em ambientes estéreis, onde não havia vestígios de organismos vivos que a ocupassem antes. Esse ambiente pode ser um local vulcânico em que a lava derretida destruiu o meio ambiente ou foi causada por dunas. A comunidade inicial de organismos para habitar esses ambientes é conhecida como sucessores primários ou colonizadores primáriosrimários

Explanation:

Primary colonisers initiate primary succession as such they are important to the future of such environments. They are though breeds of organisms that make use of scarce resources to survive in harsh environments. Without their ability to survive, there will be little or no way other forms of succession can take place. Reasons, why they may not persist, maybe too much stress imposed on them by the environment and above all their inability to compete when other successors come on board.

Answer:

They are: substrates, template, primer and enzymes. Four deoxyribonucleotide triphosphates (dNTP's) are required for DNA synthesis (note the only difference between deoxyribonucleotides and ribonucleotides is the absence of an OH group at position 2' on the ribose ring). These are dATP, dGTP, dTTP and dCTP.
