Histones copy the DNA before division begins is the correct role of histones.

A chromosome's structural support is provided by a protein called a histone. Long DNA molecules found on each chromosome must fit into the cell nucleus.

To do it, the DNA wraps around complexes of histone proteins, giving the chromosome a more compact form. Additionally, histones are involved in the control of gene expression.

A nucleosome, which is made up of eight histone proteins, can exist. DNA can loop around a nucleosome much like a small spool. Thus, histones are crucial in maintaining the genome's order and neat wrapping inside a cell.

Therefore, Histones copy the DNA before division begins is the correct role of histones.

Explanation:

All the facts and observations gathered in an experiment are called data. Therefore, option B is correct.

An experiment is a technique used to confirm or deny a hypothesis, as well as assess the likelihood or effectiveness of something that has never been tried before. Experiments show what happens when a specific factor is modified, which sheds light on cause-and-effect relationships.

The three primary categories of scientific experiments are quasi-experimental, observational, and experimental (non-experimental). The most rigorous type of scientific investigation is experimental, often known as randomized control. The most control is present, as the name would imply.

Data are the facts and the observations gathered in an experiment.  Therefore, option B is correct.

Answer:

Cystic fibrosis (CF) is more common in Caucasian individuals and is inherited with an autosomal recessive inheritance pattern.

Explanation:

Cystic fibrosis (CF) is a condition of genetic origin, which affects organs such as the lungs, pancreas, intestine and liver. CF is characterized by the production of very thick and viscous mucus, and promotes the formation of cysts and fibrosis of the affected organs.

CF is an inherited disease that is transmitted in an autosomal recessive pattern, that is, the altered gene is required to be on both chromosomes of the allelic pair, in order to be expressed.

It is a very common disease in Caucasian individuals, especially those of European descent.

Answer:

In sunlight the concentration of water and oxygen molecules just inside the stomata is higher than the concentration of the air around the leaves so water vapor and oxygen diffuse, or move out, from the leaves through the stomata. Diffusion, then, is a physical driver of transpiration. Hope this helps!

False, but be sure you read what follows.

Explanation:

False: Heart disease and Most Cancers are not viruses. Or at least as far as I know. However complicating the issue is the fact that after a viral infection, heart disease can develop.

Cancer is another example, and the answer again is not black and white. 16% of all cancers can trace their beginnings to a bacteria or virus. That leaves 84% whose beginnings are not that clear.

The question is not black and white. I'd be careful how you think of it. If something is a complication, is that a direct cause? I still think the answer is false,  but don't be surprised if your instructor disagrees. Move on to something a little less black and white.

Answer:

1. In the process of photosynthesis, plants convert the energy of sunlight into chemical energy stored in the bonds of carbohydrates.

a. The light-dependent reactions use light energy to make two molecules needed for the next stage of photosynthesis: the energy storage molecule ATP and the reduced electron carrier NADPH. In plants, the light reactions take place in the thylakoid membranes of organelles called chloroplasts.

b. In the Calvin cycle (light independent reactions), carbon atoms from CO2 are fixed (incorporated into organic molecules) and used to build three-carbon sugars. This process is fueled by, and dependent on, ATP and NADPH from the light reactions. Unlike the light reactions, which take place in the thylakoid membrane, the reactions of the Calvin cycle take place in the stroma (the inner space of chloroplasts).

2. When transitioning to respiration, photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.

3. Cellular respiration is the aerobic process by which living cells break down glucose molecules, release energy, and form molecules of ATP. Overall, this three-stage process involves glucose and oxygen reacting to form carbon dioxide and water.

a. Fermentation refers to the metabolic process by which organic molecules (normally glucose) are converted into acids, gases, or alcohol in the absence of oxygen or any electron transport chain.

4. They are similar because they both produce energy but in two different forms.

Photosynthesis- It produces oxygen and G3P, simple carbohydrate molecules that are high in energy and can be converted into glucose, sucrose, or other sugar molecules.

cellular respiration-During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water.

Explanation:

1. A process in which the plants prepares their food from inorganic compounds and light energy is called photosynthesis.

The energy stored in the carbohydrates is used in the preparation of chemical energy.

a. In reactions that use light for the process is called light-dependent reactions. It transpires in the thylakoid organelle of the chloroplast. The light is needed for the synthesis of ATP and NADPH which is a reduced electron carrier.

b. The reactions in which the carbon dioxide is fixed from the carbon source to produce three-carbon sugars is called light-independent reactions. The process of the Calvin cycle transpires in the stroma of the chloroplast.

2. When transpiration changes to the respiratory pathway then glucose is produced during photosynthesis and is used in the process of cellular respiration to produce ATP.

The produced glucose gets converted back into carbon dioxide through the process of expiration.

The water molecules get broken into oxygen during photosynthesis and in another process of cellular respiration, the oxygen combines with hydrogen to yield water.

3. The aerobic process that requires oxygen molecules to break glucose molecules in living organisms to produce ATP and releases energy is called cellular respiration.

The process comprises a reaction between glucose and oxygen to produce carbon dioxide and water.

a. The metabolic process in which the organic molecules are converted to gases, alcohol and acids in the absence of ETC or oxygen is called fermentation.

4. The process of photosynthesis and cellular respiration have similar molecules as:

In the photosynthesis process molecules produced are oxygen, carbohydrates that are high in energy and get converted to glucose or other sugar molecules. In cellular respiration, glucose gets broken into water and carbon dioxide.

Ground tissue is responsible for metabolism, storage, and support, but not transport of water or photosynthesis in the leaf.

Ground tissue is one of the three main types of plant tissue, and it is responsible for a wide variety of functions within the plant.

These functions include metabolism, storage of nutrients and water, and providing structural support.

However, ground tissue is not directly involved in the transport of water, which is primarily the role of the vascular tissue.

Additionally, while ground tissue cells may contribute to photosynthesis in some plant organs, such as the stem or root, they are not typically involved in this process in the leaf.

Overall, ground tissue plays a crucial role in the overall function and health of a plant, but its functions are distinct from those of other types of plant tissue.
