Choose one microscopic species that causes a human illness. Give the scientific name of the species, the disease it causes, and the vector, and then describe the symptoms in a 130 word paragraph or two.

Answer:

The correct answer would be 4 phases.

Mitosis is a equational division which results in the formation of two daughter cells with equal number of chromosomes as there were in parent cell. It contains four phases prophase, metaphase, anaphase, and telophase. It helps in growth and repair of the cells.

In contrast, meiosis is reductional division which leads to production of four haploid daughter cells from a single diploid parent cell. It usually takes place during the formation of gametes. It takes place in two divisions namely meiosis I and meiosis II.

Meiosis I contains four phases:

Meiosis II also contains four phases:

Explanation- Neurotic zone refers to the top layer of the ocean, from the surface of the ocean to a depth of 200 m below the ocean. It is a region where sunlight is maximum, and is a nutrient rich zone. Due to this,numerous, diverse marine life forms exist as well as the marine plants such s corals, phytoplankton and kelps can prepare their food undergoing photosynthesis process.

This neurotic zone when compared to the continental shelf in terms of height, it lies above the shelf, and the water in this neurotic zone is considered as the neurotic water.

Thus, the above statement is true.

Answer: The given statement is True.  

Human activities on land can have a profound influence on marine ecosystems. These include both direct as well as indirect activities by humans, which influence marine ecosystems.

For instance, direct human activities like use of fertilizers in agriculture can have a profound influence on the marine ecosystem. Chemical fertilizers provide extra nutrients to the plants, increasing the fertility of the soil and thereby promote the growth of plants.

These fertilizers are harmful to the aquatic lives. They travel to the marine ecosystem via water run off from the agricultural land. Excess fertilizers cause the formation of algal blooms, which are very toxic. They lead to the lack of oxygen in the water, which results in the loss of aquatic lives.

The permanent sterilization prevents sperm from reaching the egg and fertilizing it.  

Sterilization is the process of permanent birth control.

The women sterilization process s called tubal ligation.

Tubal ligation closes all the Fallopian tubes, so that sperm could not reach the uterus of the women.

The men sterilization is called vasectomy.

The human eye can see visible light in the range of 380 nm to 740 nm, which includes colors red through violet. The wavelengths outside this range, such as infrared waves, cannot be seen.

The human eye can see light with wavelengths that range from about 380 nm to 740 nm. This range includes the colors of the rainbow, which can be remembered by the mnemonic ROY G BIV - for Red, Orange, Yellow, Green, Blue, Indigo, and Violet. However, the wavelengths that fall outside of this visible spectrum, such as infrared waves, cannot be seen by the human eye. Infrared light has longer wavelengths than the visible red light, and humans perceive this as heat rather than light.

Visible light is composed of a spectrum of colors that include red light waves, blue light waves, and violet light waves. However, all wavelengths can't be seen by the human eye; specifically, infrared waves are outside the visible range. Thus, all of the listed wavelengths can be seen by the human eye except infrared waves.

Answer:

C. gametes

Explanation:

The alternation of generations is a process of reproductive cycles that occur in plants, algae and cnidarians. The main characteristic of this type of reproduction is that it happens in two different generations alternating in a single life cycle of the organisms.

For this process to occur in plants, it is necessary that there is a generation that produces spores (sporophytic generation) and a generation that produces gametes (gametophytic generation). The generation that produces spores should produce diploid cells, while the generation that produces gametes must produce haploid cells.

When haploid cells arise from the germination of spores (which are haploid), the phase called gametophytic begins in the body, where the formation of two gametes (one male and one female) occurs. These gametes will merge during fertilization, generating a diploid embryo, which will undergo several mitoses until it becomes an adult that is capable of forming spores.

Final answer:

A surgeon operating on the intestines would have to open the A) Abdominopelvic and abdominal cavities. The pleural cavity, which is associated with the lungs, is part of the thoracic cavity.

Explanation:

The question asks about the body cavity a surgeon would open to operate on the intestines. The correct answer is A) Abdominopelvic and abdominal. The abdominopelvic cavity is the largest in the body and includes both the abdominal cavity (housing the digestive organs, such as the intestines) and the pelvic cavity (housing the reproductive organs).

As for the pleural cavity, it is part of the thoracic cavity which also contains the pericardial cavity surrounding the heart. These cavities are all located within the larger anterior (ventral) cavity. Thus, a surgeon must open the abdominopelvic cavity to perform operations on the intestines.

This answer provides 10 examples each of conduction, convection, and radiation. It also explains whether combustion reactions are exothermic or endothermic, and provides an example of a substance with a higher specific heat than liquid water.

1. Touching a hot stove and feeling heat transfer to your hand

2. A metal spoon becoming hot when placed in a cup of hot soup

3. A pan heating up when placed on a stove burner

1. Boiling water in a pot on a stove

2. Wind blowing and causing heat transfer in the atmosphere

3. A radiator heating a room by transferring heat to the air

1. Feeling the warmth of the sun on your skin

2. A campfire warming your body by emitting heat

3. A microwave oven cooking food by emitting electromagnetic waves

Combustion reactions are exothermic, meaning they release heat. This is because combustion reactions involve the rapid combination of oxygen with a fuel, such as burning wood or gasoline. The release of energy in the form of heat is what makes combustion reactions exothermic.

A substance with a specific heat higher than liquid water is ethylene glycol (antifreeze). Specific heat is the amount of heat needed to raise the temperature of a substance by a certain amount. Ethylene glycol has a higher specific heat than water, which means it can absorb more heat energy before its temperature increases significantly.

Answer:

The correct answer is option b. the chromosomes line up.

Explanation:

Metaphase is the phase which takes place between prophase and anaphase. It is mitotic phase in which microtubules attached. The chromosomes line up during this phase.

Metaphase is characterized by the attachment of spindle to the chromosomes. Attachment is complete by the microtubules of spindle.

Thus, the correct answer is option b.the chromosome line up.

The tiny things that materials are made from and a quality of a substance are atoms.

Every atom is composed of a nucleus and one or more electrons bound to the nucleus. The nucleus is made of one or more protons and a number of neutrons. Only the most common variety of hydrogen has no neutrons.

An atom is a particle of matter that uniquely defines a chemical element. An atom consists of a central nucleus that is surrounded by one or more negatively charged electrons. Atoms were created after the Big Bang 13.7 billion years ago. As the hot, dense new universe cooled, conditions became suitable for quarks and electrons to form.

Atoms are indivisible particles, which cannot be created or destroyed in a chemical reaction. Atoms of a given element are identical in mass and chemical properties.

If meiosis fails to take place to produce sex cells then fertilization would result in the formation of a zygote with twice as many chromosomes as the parents.  

• The formation of the sperm and the egg cells is known as meiosis. The body cells are diploid in the sexually reproducing organisms, that is, they constitute two chromosome sets, one from each parent.  

• At the time of meiosis, the diploid cells go through the process of DNA replication, which is succeeded by two rounds of cell differentiation, giving rise to haploid sex cells.  

• In cases, when meiosis fails to take place in sexually reproducing organisms, the number of chromosomes would get double in each generation as it is the process of meiosis, which halves the chromosomes number in the gametes.  

Thus, in the given case, fertilization would lead to the formation of a zygote which would comprise twice as many chromosomes as the parents.
