Cell division occurs in all living organisms. This is known as mitosis.

The advantages of a larger organisms to subdivide themselves into smaller cells is that as all organisms grow, some of their cells die or get damaged with time and need replacements. So,it divides into smaller cells because when a cell becomes large, it demands more of cell places of its DNA. If the cell grows too large, it will have trouble moving enough nutrients and wastes across the cell membrane. So to grow properly the cells need to be divided.

Answer:

The correct answer will be- to maintain the surface area to volume which helps organism stay alive.

Explanation:

The larger organism is made up of many cells as the cell needs resources and the movement of these resources takes place through cell surface so a large surface area will favor the cell growth.

when a cell grows its requirement for sorceresses also increases which will disturb the cytoplasmic content and will cause the cell to change its volume. so both surface area to volume plays an important role in cell growth and function.

If cell grows oversize, then the cell will die which poses a threat to size of the cells thus, the small size of the cell help maintain the amount of surface area compared to volume and allows us to be alive.

The structure of a typical antibody molecule

Antibodies are the secreted form of the B-cell receptor. An antibody is identical to the B-cell receptor of the cell that secretes it except for a small portion of the C-terminus of the heavy-chain constant region. In the case of the B-cell receptor the C-terminus is a hydrophobic membrane-anchoring sequence, and in the case of antibody it is a hydrophilic sequence that allows secretion. Since they are soluble, and secreted in large quantities, antibodies are easily obtainable and easily studied. For this reason, most of what we know about the B-cell receptor comes from the study of antibodies.

Antibody molecules are roughly Y-shaped molecules consisting of three equal-sized portions, loosely connected by a flexible tether. Three schematic representations of antibody structure, which has been determined by X-ray crystallography, are shown in Fig. 3.1. The aim of this part of the chapter is to explain how this structure is formed and how it allows antibody molecules to carry out their dual tasks—binding on the one hand to a wide variety of antigens, and on the other hand to a limited number of effector molecules and cells. As we will see, each of these tasks is carried out by separable parts of the molecule. The two arms of the Y end in regions that vary between different antibody molecules, the V regions. These are involved in antigen binding, whereas the stem of the Y, or the C region, is far less variable and is the part that interacts with effector cells and molecules.

How does light intensity affect oxygen production?

ZanzabumX [31]

Greater light intensity would mean a faster rate of photosynthesis in plants. photosynthesis takes in carbon dioxide and water to produce glucose and oxygen. therefore, a greater light intensity would mean faster oxygen production

Which regions best identifies where myosin would have maximum cross-bridge access to actin?

8090 [49]

<h2>Region between 2 and 3</h2>

Explanation:

Muscles consists of two protein filaments:a thick filament which is made up of protein myosin whereas a thin filament is made up of protein actin

During contraction,thin filaments slide past the thick filament resulting in shortening of sarcomere
Myosin thick filaments grab on to the actin filaments by forming cross bridges
The thick filaments pull the thin filaments past them making the sarcomere shorter
The region between points 2 and 3 includes the area of overlap between thin and thick filaments

When making yogurt, bacteria and milk are mixed together and set in a warm area. The container is sealed and no gasses are allow

Ivenika [448]

Answer:

When making yogurt the tart flavor get in the end is more likely because the bacteria have carried out a type of respiration named lactic acid fermentation (option C).

Explanation:

The process of obtaining yogurt from whole milk involves the association of the bacterial species Streptococcus and Lactobacillus. In order to carry out the lactic acid fermentation that produces yogurt, the bacteria act in a different way:

Streptococcus is in charge of removing the oxygen from the milk product.
Lactobacillus promotes the conversion of lactose sugar into lactic acid.

This fermentation process leads to the conversion of milk into a coagulated and tart flavor product.

Other options are not correct because:

A. Photosynthesis : is the process that occurs in plants to obtain chemical energy from sunlight.

B. Alcoholic fermentation: in this chemical process alcohol is obtained from the fermentation of a sugar.

D. Aerobic cellular respiration: does not involve fermentation, but the series of processes that convert glucose into energy.

What feature of both true mosses and ferns makes it most surprising that they can survive for many generations in dry deserts? U

FromTheMoon [43]

Answer:

The correct answer will be option-A

Explanation:

Desert biomes are characterised by the presence of the arid conditions or with few or less amount of rainfall.

The plant groups called the bryophytes and pteridophytes are dependent on the water for their fertilization which allows completing their life cycle.

In the desert conditions provided in the question, the mosses and ferns survived for many generations as these plant groups produced sperms with flagella which helped the sperms to swim in the water provided by the 10-inch rainfall per year and reach the female gamete and fertilize the egg cell.

Thus, option-A is the correct answer.
