(b) No. HIV can only be caught by another person of they come in contact with your blood or through sexual intercourse. So it is not possible for others to become infected if they didn't come in contact with the person's blood or have unprotected intercourse. There is no reason for a HIV+ve person to isolate themself from the outside world. They are people just as we are but they only have something that can cause them to be really sick.

Answer:

1, Planting trees

2. Actions that reduce carbon dioxide emission

Explanation:

Ally can reduce the amount of carbon dioxide in the atmosphere in two ways

1. By planting trees or reforestation

Trees generally act as a sink for carbon through photosynthesis. Hence, planting more trees means that more carbon dioxide in the atmosphere will become fixed into the trees leading to the reduction of the gas in the atmosphere.

2. Reducing emission

To further reduce the amount of carbon dioxide in the atmosphere, the rate of emission of the gas has to be reduced. Actions such as the burning of vegetation and fossil fuels need to be reduced because they increase the emission of carbon dioxide gas into the atmosphere. The actions can be substituted for less or no carbon dioxide emitting alternatives.

When less carbon dioxide is emitted into the atmosphere and more is being fixed into trees, the overall concentration of the gas in the atmosphere will reduce greatly with time.

Endoplasmic reticulum

Explanation:

The endoplasmic reticulum is a network of passageways found in the cytoplasms of eukaryotes for the purpose of manufacturing, processing, transporting, modifying, and folding proteins. There are two types of endoplasmic reticulum and they are the smooth and rough endoplasmic reticulums.

Unlike the smooth endoplasmic reticulum, the rough endoplasmic reticulum has ribosomes attached to it.

Explanation:

Answers and explanation:

Most of the cells in the human body are somatic cells and have 23 pairs of chromosomes (46 chromosomes in total) and are thus called 'diploid cells'. The only cells that have 23 single chromosomes are the gametes, which are haploid cells - the reason behind this is that gametes in females (ovum) need to be fertilized by the gametes present in males (sperm) to form a new being: the zygote.

Mitosis and meiosis are both processes in which the cells are divided, but they are quite different. In Mitosis, the somatic cells divide themselves to generate two daughter cells that are equal to the cell that has divided. In Meiosis, the diploid cells that generate the gametes, divide into four daughter cells, which will all have half of the chromosomes (the four of them will be haploid cells with 23 chromosomes each).

1. How many daughter cells are made during mitosis? 2.

During meiosis? 4.

2. In humans how many chromosomes will be in a daughter cell after mitosis? 46. After meiosis? 23.

3. What happens during interphase before both mitosis and meiosis can begin?

Interphase is the name given to the part of the cell cycle in which the cells are not dividing themselves. In this phase, cells spend most of their lives, and they use it to do things such as obtaining nutrients and metabolizing them so they can make use of them to carry on with their specific tasks, which vary depending on the type of the cell. In a very specific part of Interphase called the S phase, the cell duplicates its DNA - this leads to the cell having 2 copies of the same information, which will be important when cell division comes (in Mitosis, each daughter cell will get one complete copy; in Meiosis, each daughter cell will have half of a copy).

Answer:

It is still important, because photosynthesis produces oxygen which is what we breathe.

Photosynthesis is also necessary to grow food, which is what we eat

True these are both examples of food produced through alcoholic fermentation.

The chemical reaction that produces alcohol is known as alcoholic fermentation. In essence, beer, wine, sake, and cider all begin with yeast eating a type of sugar, which is the basis for this process.

Even hard liquors, such as your preferred tequila, begin with a straightforward alcoholic fermentation.

Alcoholic fermentation produces three primary byproducts. Alcohol, which has historically been a crucial component of beer, wine, and hard cider, is one of them, which is not surprising.

-Worldwide sea level increased

-river plains drowned

Explanation

Glaciers are large blocks of ice and with all the ice melting the water levels rose worldwide. (Correct Answer)

When sea levels rose it caused river plains to be flooded. (Correct Answer)

Glaciers are made from freshwater so when they melt the salinity in estuaries does change. (Not a correct Answer)

Erosion definitely affected river valleys. Alpine glaciers create valleys and even help erode valleys. With Alpine glaciers melting this slows the process of that erosion and with them melting the river valleys will eventually flood. (Not a correct Answer)

Answer:

adherence of phagocytes to the lining of blood vessels

Explanation:

The correct answer for the medical/biological definition of margination would be the adherence of phagocytes to the lining of blood vessels.

Margination is a process that takes place when injuries occur in complex animals. During the early phase of inflammation of the injury site, the blood capillaries dilate and the white blood cells (phagocytes and leukocytes) adhere to the endothelial cells of blood vessels.

Answer:

a. capillary action of liquid in plant stems

Explanation:

Vascular plants need to transport water from roots to stem and leaves. For this purpose, water molecules adhere to xylem cell walls (xylem is one of the two classes of transport tissues in higher plants). Adhesion, also known as capillary action, is a mechanism produced when water molecules cling to xylem cell walls. Thus, adhesion can be defined as a molecular mechanism caused by the attraction between molecules, in this case, between molecules of the xylem and water molecules.

Mobility.

Explanation:

Mobility is the term used for all types of movement such as walking , running, swimming and flying etc. Mobility refer to the movement, those organisms which has the ability to move from one place to another is known as mobile organisms e.g lion, birds, tiger and humans etc, while on the other hand those organisms that are unable to move from place to place is called immobile organisms.

Answer: During the process of transcription, the information stored in a gene's DNA is transferred to a similar molecule called RNA (ribonucleic acid) in the cell nucleus. ... A type of RNA called transfer RNA (tRNA) assembles the protein, one amino acid at a time.

The sequence of nucleotides of DNA directs the formation of the structure of proteins. The information stored in the DNA is transferred to the RNA by transcription and the RNA forms the proteins.

The process of the creation of protein molecules is called protein biosynthesis. Amino acid synthesis, transcription, translation, and post-translational events are the steps that are involved in protein synthesis. In the case of amino acid synthesis, a set of biochemical processes happen and they produce amino acids from various carbon sources like glucose.

In the case of biological systems, protein synthesis happens inside the cell. In the case of prokaryotes, it occurs in the cytoplasm. In eukaryotes, it happens in part in the nucleus and partly in the cytoplasm.

The transcript is formed in the nucleus and leaves the nucleus to reache the ribosomes and it is translated there and forms a protein molecule that has a specific sequence of amino acids.

The creation of proteins by cells uses DNA, RNA, and various enzymes. Usually, it includes the events like transcription, translation, and post-translational events. These are protein folding, modifications, and proteolysis.

Therefore, the sequence of nucleotides of DNA directs the formation of the structure of proteins. The information stored in the DNA is transferred to the RNA by transcription and the RNA forms the proteins.

Answer:

Autosomal dominant pattern.

Explanation:

If the pattern of inheritance is same in the disease just like the model of colorblindness mutation so we can say that the disease has autosomal dominant pattern because the colorblindness mutation also occur due to the autosomal dominant pattern. Sometimes the disease is also inherited from their parents through genetically. So both diseases and the model colorblindness mutation are considered same if both have the same pattern of inheritance.
