Research how coral reefs are formed. What types of animals live there? What important roles do cnidarians play in coral reefs? How do the tiny animals get their food? How do algae help the corals? Write a three-paragraph essay describing coral reefs.
Answers
Answer:
Fish, corals, lobsters, clams, seahorses, sponges, and sea turtles are only a few of the thousands of creatures that rely on reefs for their survival. Cnidarian ecology is a complex subject indeed, because it is cnidarians, in particular corals, that are the builders of some of the richest and most complex ecosystems on the planet, coral reefs. Corals get their food from algae living in their tissues or by capturing and digesting prey. Corals also eat by catching tiny floating animals called zooplankton. At night, coral polyps come out of their skeletons to feed, stretching their long, stinging tentacles to capture critters that are floating by. The corals and algae have a mutualistic relationship. The coral provides the algae with a protected environment and compounds they need for photosynthesis. In return, the algae produce oxygen and help the coral to remove wastes. This is the driving force behind the growth and productivity of coral reefs.
How Coral Reefs are described.
A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. They are most found at shallow depths in tropical waters, but deep water and cold-water coral reefs exist on smaller scales in other areas. The algae also give a coral its color; coral polyps are transparent, so the color of the algae inside the polyps show through. Coral reefs provide habitat for a large variety of marine life, including various sponges, oysters, clams, crabs, sea stars, sea urchins, and many species of fish. Coral reefs provide an important ecosystem for life underwater, protect coastal areas by reducing the power of waves hitting the coast, and provide a crucial source of income for millions of people. Coral reefs teem with diverse life. Thousands of species can be found living on one reef. A coral reef is an underwater ecosystem characterized by reef-building corals.

Answer:
Proton
Explanation:
Neutron are neutral, ion I am not sure but are not positive, and electron are -.
Answer: Proton
Explanation:
In an atom there exist three types of sub atomic particles
1) Electrons
2) Neutrons
3) Protons
so we know that electrons are negatively charged particles which stays in a finite orbit as per their energy level
Protons are positively charged particles which remains inside the nucleus and they are tightly bound inside it
Neutrons are neutral sub atomic particles which do not have any charge in it.
So we have correct answer as

In fruit flies normal wings (W) is dominant over vestigial wings (w). The results
of a cross, of two fruit flies, give the following results:
Normal wing 793 Vestigial wing 811
Answers
The possible genotype of the parents is most likely Ww and Ww, option D is correct.
The given data represents a phenotypic ratio of 793:811, which is approximately a 1:1 ratio. This suggests that the parents were most likely heterozygous for the wing size gene. In fruit flies, normal wings (W) are dominant over vestigial wings (w), and the genotypes that produce normal wings are either homozygous dominant (WW) or heterozygous (Ww), whereas the genotype that produces vestigial wings is homozygous recessive (ww).
The possible genotype of the parents can be Ww and Ww, or WW and Ww. A cross between Ww and Ww would result in a phenotypic ratio of 3:1, whereas a cross between WW and Ww would result in all offspring with normal wings (WW or Ww). As the observed ratio is closer to 1:1, it is more likely that the parents were heterozygous (Ww), option D is correct.

Explanation:
In this division, the secondary spermatocytes and oocytes, which contain 23 chromosomes each and are diploid in the amount of DNA, are divided into two cells, each of which will have 23 chromosomes, but twice the amount of DNA, since in anaphase there was a separation chromosome to sister chromosomes, reducing the amount of DNA by half.
As a result of this division in males in the process of spermatogenesis from the initial, diploid spermatogonia or primary spermatocytes, 4 cells are formed - spermatids that have a haploid number of chromosomes and twice less DNA than the cells from which they were formed.

the enzyme-containing cap on the head of a spermatozoon is called the
Answers
The enzyme-containing cap on the head of a spermatozoon is called the acrosome.
The acrosome is a specialized structure found on the head of a spermatozoon (sperm cell).
1. Spermatozoon: Spermatozoa, or sperm cells, are the male reproductive cells responsible for fertilizing an egg during sexual reproduction.
2. Structure of Sperm: The head of a spermatozoon contains the genetic material (DNA) that carries the father's genetic information. It is covered by a cap-like structure called the acrosome.
3. Acrosome: The acrosome is a membrane-bound organelle located at the tip of the sperm's head. It is derived from the Golgi apparatus during spermatogenesis, the process of sperm cell development.
4. Enzymes in the Acrosome: The acrosome contains various enzymes, including hyaluronidase and acrosin, which are involved in the process of fertilization.
5. Function: The acrosome plays a vital role in fertilization. When a sperm reaches the vicinity of an egg, the enzymes within the acrosome are released. These enzymes help the sperm penetrate and break down the protective layers surrounding the egg, allowing it to fuse with the egg's plasma membrane.
6. Fusion and Fertilization: Once the sperm's head penetrates the egg's protective layers, the genetic material from the sperm combines with that of the egg, resulting in the formation of a zygote, which is the initial stage of a new individual.
In summary, the enzyme-containing cap on the head of a spermatozoon is called the acrosome. It contains enzymes necessary for the sperm to penetrate the protective layers of the egg during fertilization. This process is essential for successful reproduction in sexually reproducing organisms.

Answers
(a) When the male sex cells, or sperm, join with the female sex cells, or egg, from another pea plant, a new organism begins to form. This is called sexual reproduction.
(b) The pistil of another plant is when pollen from a plant lands on the stigma of a different plant, allowing for fertilization to occur and for seeds to be produced.
What is Sexual reproduction?Sexual reproduction is a process of reproduction that involves the fusion of gametes, which are haploid cells with half the number of chromosomes found in a normal diploid cell.
In plants, the male gamete is the sperm cell, which is produced in the anther of the flower, while the female gamete is the egg cell, which is produced in the ovule of the flower.
When a pollen grain lands on the stigma of a flower, it germinates and produces a pollen tube that grows down the style towards the ovary. The sperm cells inside the pollen tube then fertilize the egg cells in the ovule, resulting in the formation of a zygote, which develops into an embryo.
The ovule also develops into a seed, which contains the embryo, and the ovary develops into a fruit that protects and disperses the seed.

The ________ deliver(s) blood to the myocardium
Answers
The coronary arteries deliver blood to the myocardium.
The myocardium, which refers to the muscular tissue of the heart, requires a constant supply of oxygen and nutrients to function properly. The coronary arteries are responsible for delivering oxygenated blood to the myocardium, ensuring its nourishment and oxygenation. The heart has its own network of blood vessels, known as the coronary circulation, which branches off from the main systemic circulation. .
The coronary arteries are crucial for maintaining the health and functionality of the myocardium. When the heart is at rest, these arteries supply a constant flow of oxygenated blood to meet the myocardium's metabolic demands. During periods of increased activity or stress, such as during exercise or emotional arousal, the coronary arteries can dilate to allow for an increased blood supply to meet the heightened oxygen and nutrient requirements of the myocardium.

List three effectors that are used to lower your body's temperature
Answers
Answer: To lower your body's temperature, there are three main effectors that can be used: sweating, vasodilation, and shivering. Sweating allows the body to release heat through the evaporation of water on the skin's surface. Vasodilation dilates the blood vessels in order to increase blood flow to the skin and allow more heat to be lost from the body. Lastly, shivering increases metabolism and generates heat that can be released from muscle activity.
