Answer 1

Answer:

Option 1: XnY

Explanation:

X-linked recessive traits can occur in both males and females. Since its recessive it needs both XnXn in females to show up but for males who are hemizygous (XY) they only need a defective copy of Xn for the disease to show up thus option 1 is correct.

I have added a helpful illustration below where we are talking about another x-linked recessive condition in humans: hemophilia.

Aquaporins

Explanation:

This is because osmosis is the movement of solutes from a region of lower concentration to a region of higher concentration through a permeable membrane.

Aquaporins are lipid bilayer and water pores that serve as channels of transmembrane proteins that allow water to cross the membrane very fast, and they play vital roles red blood cells, plant cells and kidney which help to reduce water lose.

Plants play a role in this cycle by completing photosynthesis:

Answers

Answer:Plants don't eat food; they have to create it for themselves. They do this through a process known as photosynthesis. Photosynthesis uses water, carbon dioxide from the air and energy from the sun or another light source to create glucose or sugar.

What gets passed through the electron transport chain and both photosystems to create energy?
A. electrons
B. oxygen
C. pigments
D. ATP​

Answers

Answer:

A. electrons

Explanation:

Energy in form of ATP is generated at both cellular respiration and photosynthesis. In cellular respiration, energy (ATP) is synthesized in the mitochondria when ELECTRONS (e-) passes through series of complexes composed of proteins called ELECTRON TRANSPORT CHAIN.

On the other hand, ATP is synthesized when ELECTRONS produced from splitting water i.e photolysis of water, passes through photosystems 1&2 in the chloroplast (thylakoid).

Answer: Electrons

Explanation: The electron transport chain is a series of molecules that accept or donate electrons easily

what are the most common c0vId vaccine myths and how did they start? Explain your answer.

Answers

Answer:

The most common myths are:

- C0vid2019 vaccines cause autism  

- C0vid2019 vaccines may modify your DNA

- C0vid2019 vaccines are unsafe

Explanation:

The most common myths associated with C0vid2019 vaccines are:  

1- C0vid2019 vaccines may cause autism: In 1998, Andrew Wakefield and colleagues published a controversial study in the Lancet where they suggested that the measles, mumps, and rubella (MMR) vaccine may cause autism in some children. However, it has been showed that this study was based on erroneous statements and therefore this publication was retracted.

2- C0vid2019 vaccine may modify your DNA: it has been suggested that vaccines based on viral vectors (e.g. adenoviruses) and mRNA vaccines may modify the DNA of cells. This statement is false because these technologies cannot alter the DNA sequence. These vaccines are based on the production of an mRNA sequence that is translated into a viral protein (spike protein) which triggers an immune response

- C0vid2019 vaccines are unsafe: some people believe that C0vid2019 vaccines are unsafe because they were developed quickly. However, this statement is false because all vaccines (including C0vid2019 vaccines) need to follow rigorous safety standards to be approved by governmental agencies (i.e., they approved all clinical trials).

13. If a stream or river stops flowing due to water scarcity, what disease may result from the stagnant water?
malaria
hunger
sickle cell anemia
lung cancer

Answers

“Malaria and dengue are among the main dangers of stagnant water, which can become a breeding ground for the mosquitoes that transmit these diseases.”

If a stream or river stops flowing due to water scarcity, the disease that will be caused by the stagnant water is malaria. The correct option is A.

What is malaria?

Malaria is a disease that is caused by a protist, called plasmodium. It has four species and all give malaria. It is transmitted by mosquitoes because plasmodium lives in mosquitoes.

Stagnant water is stored water in a place for a very long time. The water of a river or s stream is stopped by dams sometimes. This water is the home to many insects to lay their eggs, like, mosquitoes.

Mosquitoes lay their eggs in water bodies or stop water, so they will lay their eggs in the stagnant water. It will increase the population of mosquitoes and with the increase in mosquitoes, there will be an increase in the cases of malaria.

Thus, the correct option is A. malaria.
