Answers

Answer:

Sperm + egg----- zygote.

Explanation:

During sexual reproduction, a male sperm fuse with female eggs forming a new organism. Male sperm and female eggs have haploid number of chromosomes but when they fuse with each other a zygote will formed having diploid number of chromosomes. The gametes of male and female have haploid number of chromosomes due to meiosis cell division.

All of the major components of the light reactions, including the pigment molecules
clustered in photosystems I and II, are located in the thylakoid membrane. What is the advantage of
having these components confined to the same membrane rather than dissolved in the stroma or the
cytosol/cytoplasm? Explain your argument. (up to 5 points)

Answers

Answer:

Having the light reaction components in close proximity speeds up the process. Electrons move from one protein to the next in sequence. If the proteins had to 'swim' around to find the next part of the electron transport chain, then the ATP would form at a much slower, inefficient rate.

what happens during G1 phase?

Answers

Answer:

G1 phase. G1 is an intermediate phase occupying the time between the end of cell division in mitosis and the beginning of DNA replication during S phase. During this time, the cell grows in preparation for DNA replication, and certain intracellular components, such as the centrosomes undergo replication.

Explanation:

During G1 phase, the cell grows in size and synthesizes mRNA and protein that are required for DNA synthesis. Once the required proteins and growth are complete, the cell enters the next phase of the cell cycle, S phase. The duration of each phase, including the G1 phase, is different in many different types of cells.

Brown bear Sun bear Spectacled bear Giant panda Lesser panda Raccoon Dog 100 0 So 60 40 20 Mulions of Years Ago 13 Which statement is best supported by the information in this dendrogram?​

Answers

Answer: C

Explanation: Lesser pandas are more genetically similar to raccoons that they are to giant pandas.

The statement "Lesser pandas are more genetically similar to raccoons than they are to giant pandas" is not fully supported by the information in the dendrogram presented above.

What does the dendrogram suggest basically ?

While it is true that the dendrogram suggests that the giant panda and lesser panda share a more recent common ancestor than either does with the other bears or the raccoon dog, it does not provide evidence to support the claim that the lesser panda is more genetically similar to raccoons than to giant pandas.

The dendrogram provides evidence for the evolutionary relationships among these organisms based on their DNA and RNA sequences. It suggests that these organisms have a common evolutionary history and can be grouped together based on their molecular data.

However, it does not provide information on the degree of genetic similarity between any two specific organisms or groups of organisms.

Therefore, while it is possible that the lesser panda may be more genetically similar to raccoons than to giant pandas, this claim cannot be fully supported by the information in the dendrogram alone.

Further analysis of genetic data and comparison of specific genetic sequences would be necessary to determine the degree of genetic similarity between these organisms.

If an air mass is sinking, it must be
A. cold and less dense
B. warm and more dense
C. cold and more dense
D. warm and less dense

Answers

Answer:

The awnser to your question is C.

Explanation:

The colder matter is the atoms get closer therefore making the matter more dense. A. is half correct but if the matter is cold it wouldn't be more dense because when something is less dense it goes above whatever is around it. Take for example water and oil. They seperate into different layers due to density.     Hope this helps. :)

The airmass is a large homogenous mass of air over a region that could be for many days.

The volume of air is defined by the temperature and water vapor content. Airmass may spread from hundreds to miles and are classified according to latitude and altitude. There are 4 types of air mass artic, tropical equatorial, and polar. The airmass that is light is warm and has a low pressure always lifts upwards. The cold and cool airmass always settles as it's dense and heavy. Hence the option C is correct.

1. If your child had a child with a man with sickle cell disease, predict whether that child
would also have sickle cell disease. Explain the reasoning and describe the information
you used to make your prediction.

Answers

Answer:

Sickle cell disease (SCD) is a blood disorder that a child is born with. It's passed down through a parent’s genes. Children with SCD make an abnormal type of hemoglobin. This is the protein in red blood cells that carries oxygen to all parts of the body. With SCD, the body organs and tissues don’t get enough oxygen.

Explanation:

Healthy red blood cells with normal hemoglobin are round and move easily through blood vessels. When a child has SCD, the red blood cells are hard and sticky. They are shaped like the letter C (and like a farm tool called a sickle). These damaged red blood cells (sickle cells) clump together. They can’t move easily through the blood vessels. They get stuck in small blood vessels and block blood flow. This blockage can cause pain. It can also damage major organs.

Sickle cells die sooner than healthy cells. Normally the spleen helps filter infections out of the blood. But sickle cells get stuck in this filter and die. Having fewer healthy red blood cells causes anemia. The sickle cells can also damage the spleen. Without a healthy spleen, children are more at risk for serious infections.

There are several complex types of the sickle cell gene. Some don’t cause symptoms or severe problems, but others do. Talk to your child’s healthcare provider about the specific form of sickle cell your child has.

Most children with SCD will start showing symptoms during the first year, often around 5 months.

Answer:

IN my opinion I dont really thinkthe child would have ssickle cell because the mother or father dont  have it, its  only one part of its family have it but if the one part of its family sickle cell jeans is storng thn yes the child may get it .
