What are some of the ways that parasites have adapted to transmission between hosts and resisting the host’s attempts to get rid of the parasite? How do these particular developments help the parasite?

Answers

Answer for you
Organisms depend on other species for resources such as nutrients. Parasites live in or on another organism, which is called the host. The parasite takes what it needs from the host but the host receives nothing in return and often suffers as a result. An example of parasitism is the relationship between fleas and dogs. Fleas live on dogs and feed on their blood. The dog receives no benefit but the fleas are provided with food and a habitat. Fleas attach themselves to hairs and can spread from one host to another by jumping huge distances.

Once blood tonicity is negatively impacted, can the consequences be reversed?

Answers

Answer:

No.

Explanation:

Once blood tonicity is negatively impacted, the consequences can't be reversed because this tonicity permanently damaged the cell. For example, in hypotonic solution, If the water continues to move into the cell due to high solute concentration, it can damaged the cell membrane, the cell bursts and dies. But it can be reversed if the cell loses its water and become shrink in hypertonic solution and regain its original size by normalizing the water level.

Explain how salinity can make water move

Answers

Answer:

Through concentration gradients and a semi-permeable membrane.

Explanation:

Imagine a semi-permeable membrane splitting a beaker into two sides which only water can pass through and salt cannot.

One side is filled with much more salty water than the other. (the saltiness, not the amount of water).

Since the salt cannot pass through the membrane, one side's salt is much more concentrated than the other.

In an effort to restore equilibrium, more water passes to the saltier side to balance out the ratio of water : salt.

Since one side has more salt, more water is needed to balance that out, and hence water moves towards the saltier side.

NEED THIS ASAP!!!! Define: Meiosis, Sister chromosomes, homologous chromosomes

Answers

Answer:

meiosis- a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant spores.

sister chromosomes- A sister chromatid refers to the identical copies (chromatids) formed by the DNA replication of a chromosome, with both copies joined together by a common centromere.

homologous chromosomes- Homologous chromosomes are two pieces of DNA within a diploid organism which carry the same genes, one from each parental source.  Each parent provides the same 23 chromosomes, which encode the same genes.

Answer:

Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. These cells are our sex cells – sperm in males, eggs in females. ... These four daughter cells only have half the number of chromosome

A sister chromatid refers to the identical copies formed by the DNA replication of a chromosome, with both copies joined together by a common centromere. In other words, a sister chromatid may also be said to be 'one-half' of the duplicated chromosome. A pair of sister chromatids is called a dyad

homology is similarity due to shared ancestry between a pair of structures or genes in different taxa.

Chromosomes are the things that make organisms what they are. They carry all of the information used to help a cell grow, thrive, and reproduce. Chromosomes are made up of DNA. Segments of DNA in specific patterns are called genes. You will find the chromosomes and genetic material in the nucleus of a cell.

For which of the following problems would a crop rotation of various grains and legumes be an appropriate solution?
I. The nutrients in the soil on a farm are being depleted.
II. Over-irrigation is waterlogging the soil on a farm.
III. A particular kind of pest is infesting the soil on a farm.

II only
III only
I and II only
I and III only

Answers

Answer:

I and III only

Explanation:

Crop rotation is a farm practice that involves cultivating different species of crops on the same land at different seasons. In other words, the different crops are rotated. Crop rotation is done for various reasons including; improvement of soil fertility, pest and disease control etc.

In this case, a crop rotation of various grains and legumes would be an appropriate solution for the following problems:

- The nutrients in the soil on a farm are being depleted: Legumes are known to be rich in nitrogen and hence add nitrogen to the soil due to the nitrogen-fixing microbes in their roots. Hence, rotating between grains and legumes can help return the depleted nutrients (by grains) to the soil.

- A particular kind of pest is infesting the soil on a farm: Most pests are usually crop-specific, hence, planting only one type of crop can make that soil be infested with a particular kind of pest. However, rotating between crops such as grains and legumes can make a particular pests become scarce or less populated.

Carbs Provide Your Body With Energy

Glucose in the blood is taken up into your body's cells and used to produce a fuel molecule called adenosine triphosphate (ATP) through a series of complex processes known as cellular respiration. Cells can then use ATP to power a variety of metabolic tasks.

Functions of Lipids in the Body: Storing Energy

The excess energy from the food we eat is digested and incorporated into adipose tissue, or fatty tissue.

Protein makes up the building blocks of organs, muscles, skin, and hormones. Your body needs protein to maintain and repair tissues. Meanwhile, children need it for growth. Studies show that eating protein can also help you lose weight and belly fat while increasing your muscle mass and strength.

Tobacco products have been identified as mutagens. However, some tobacco users develop cancer and some do not. The reason for this apparent inconsistency is mutagens only have the capability to cause mutations if exposure lasts over 20 years some people are more predisposed to developing cancer when exposed to mutagens not all tobacco products are cancerous tobacco use only causes benign tumors that are identified as non-cancerous

Answers

Answer:

The correct statement is that some of the individuals are more predisposed to developing cancer when exposed to mutagens.

Explanation:

A single change or alternation or multiple variations within the genome of the living species is termed as a mutation, and the agent, which results in mutation is known as a mutagen. The products of tobacco are considered as mutagens. It is witnessed that some of the individuals who smoke develop cancer, while some do not. It is generally because some of the individuals are more predisposed to developing cancer when getting exposed to mutagens.  

When an individual is more likely to develop cancer in his or her entire life because of certain genetic and other factors is termed as cancer predisposition. A genetic susceptibility also known as a genetic predisposition can be illustrated as the likelihood of developing a specific disease based on the individual's genetic makeup.  

The individuals who develop cancer generally have family members who exhibited certain kinds of cancer and thus they have greater chances of getting the disease too. This is the reason that the predisposed individuals to cancer have a greater chance of developing cancer when they encounter mutagens and this is the prime reason to illustrate the fact that some of the users develop cancer, while others do not.

WHAT IS GEOTROPISM?

The parts of a plant can be divided into shoot and roots. The root of the plant is the part that grows below the ground surface in order to anchor the plant.

When a seed germinates, the root part of that seed grows towards gravity i.e exhibits geotropism while the shoot part grows away from gravity i.e. upwards.

Hence, if a seed is planted upside down, it will still grow into an erect mature plant because the root will grow downwards towards gravity (positive geotropism) while the stem grows upward away from gravity (negative geotropism).
