How have rising ocean temperatures affected coral communities?

A. Corals become less photosynthetic as the surrounding temperature increases.

B. Corals find fewer food sources when algal blooms increase due to warmer waters.

C. Corals attract fewer algal species when they become warmer.

D.Corals become bleached as they expel algae with increased temperatures.

Answers

Answer: D.Corals become bleached as they expel algae with increased temperatures.

Explanation:

As ocean temperatures rise, it can stress coral polyps, that causes them to lose algae. As a result, there is "coral bleaching". It is called that because the algae gives coral its color. When all the algae is gone, the coral is white.

The bleaching of corals in the world, are due to the increase in sea temperatures, but to understand how this changes corals, we need to know that.....

Coral bleaching

Coral bleaching is a serious ecological problem mainly related to the increase in ocean water temperature. This problem can occur transiently or fatally, killing the coral. In the bleaching phenomenon, the corals become translucent, making it possible to verify the calcium carbonate skeleton of these animals. This happens because of the expulsion of zooxanthellae algae or because of the loss of pigment from these algae, which live in a mutualistic association with the coral.

Question answer

D.Corals become bleached as they expel algae with increased temperatures.

with this information, we came to the conclusion that with the increase in sea water temperature, algae that are associated with corals are expelled.

Which cell type undergoes terminal differentiation?

Answers

Stem cells are the only form of cell that can differentiate into more specialized cell types. Therefore, they undergo terminal differentiation.

What is terminal differentiation?

As cells migrate to the surface and fully differentiate, i.e., as they keratinize and eventually die, this process is known as terminal differentiation. Terminal differentiation is a method of describing that the cells change their phenotypic traits.

During the process of terminal differentiation, several cell types (such as neurons, skeletal and cardiac myocytes, adipocytes, and keratinocytes) acquire specific tasks and ultimately exit the cell cycle. This process may be observed in neurons, adipocytes, and keratinocytes.

Answer:

Tissue that gives strength and structure to bones. Bone is made up of compact tissue (the hard, outer layer) and cancellous tissue (the spongy, inner layer that contains red marrow). Bone tissue is maintained by bone-forming cells called osteoblasts and cells that break down bone called osteoclasts. Bones also contain blood vessels, nerves, proteins, vitamins, and minerals. Also called osseous tissue.

A quick anatomy of the bone! (extras)

Anatomy of the bone. The bone is made up of compact bone, spongy bone, and bone marrow. Compact bone makes up the outer layer of the bone. Spongy bone is found mostly at the ends of bones and contains red marrow. Bone marrow is found in the center of most bones and has many blood vessels. There are two types of bone marrow: red and yellow. Red marrow contains blood stem cells that can become red blood cells, white blood cells, or platelets. Yellow marrow is made mostly of fat.

Explanation:

They consume food and they have much higher metabolism. That means that more waste products are produced. Plants can use much of the waste produced and it is in fact raw material. Animals don't normally produce their own chemicals from scratch like plants normally do so they can't just recycle the waste. They need to remove it. About the only waste plants need to get rid of is excess oxygen produced during the day. That is actually three reasons but recycling is related to plants not consuming but making their own chemicals from scratch. In a way it pretty much comes down to one main reason.

Cholera bacteria causes sever diarrhoea. These bacteria spread rapidly when sewage is not piped away. Why is this?​

Answers

A bacterium called Vibrio cholerae causes cholera infection. The deadly effects of the disease are the result of a toxin the bacteria produces in the small intestine. The toxin causes the body to secrete enormous amounts of water, leading to diarrhea and a rapid loss of fluids and salts (electrolytes).

Answer:

Because cholera bacteria rapidly multiplies in areas with improper sanitation and untreated water that people can drink.

When people drink this water, they get severe diarrhoea.

because one original strand of the double-stranded helix is found in each daughter molecule, the replication process is called

Answers

Because one original strand of the double-stranded helix is ​​found in each daughter molecule, the replication process is called semiconservative.

Replication is the process by which a DNA molecule generates two identical to itself, and is key in cell reproduction.

All cells in the body must have the exact same genome (as in asexual reproductive organisms, which are practically clones of each other) and this is achieved through replication.

The process consists of separating the two strands of DNA, each of which will function as a template to synthesize a new one.

That is, each of the two strands of DNA serves as a template to synthesize a new complementary strand of the template.

In the end, two DNA molecules are formed, each of the two DNA molecules has a new chain and one original strand, this mode of replication is called semi-conservative.

Therefore, we can conclude that because one original strand of the double-stranded helix is ​​found in each daughter molecule, the replication process is called semiconservative.

During one year, the birthrate in a country is 28 births per 1000 people, and the death rate is six deaths per 1000 people. What is the population growth rate?

Answers

Answer: 22

Explanation: 28/1000-6/1000=22/1000

Birth rate is the births per 1000 people which is subtracted by the death rate which is the deaths per 1000 people, this phenomenon is known as Population growth rate. So, 22/1000 is the population growth rate for this.

What is Birth Rate?

Birth rate is the total number of people born per year per 1000 in the population. Birth rate is also known as Natality.

For example, if 65 births occur per year per 1000 individuals, the birth rate is 65. If it is expressed in the percentage, it is 6.5 per 100 or 65%.

Population is divided into many parts like Juveniles (Period before puberty), adults and Post reproductive adults. Birth rate is higher than the death rate as the population is younger, the faster that population grows.

When the birth rate is expressed as per the age group, this is called the standardized birth rate. Birth Rate is determined by the ratio between the number of live births in a population during a year and total mid-year population for the same year multiplied by 1000.

Thus, birth rate is the births per 1000 people which is subtracted by the death rate which is the deaths per 1000 people, this phenomenon is known as Population growth rate. So, 22/1000 is the population growth rate for this.

Answers

The definition of Epistasis in gene biology is Choice D: when the allele of one gene masks the phenotype of another gene

Definition:

When the phenotypic effect of alleles at one gene are masked by alleles of another gene.

In essence, a gene is said to be epistatic when its presence suppresses the effect of a gene at another locus.

It is important to know that Epistatic genes are often called inhibiting genes because of their effect on other genes which are described as hypostatic.

Dominant

Dominant inhibitory,

Duplicate dominant,

Duplicate recessive,

Polymeric gene interaction,
