Hello, if anyone sees this, can you answer this question for me?

Each cell, expresses, or turns on, only a fraction of it's genes. The rest of the genes are repressed, or turned off. The process of turning genes on and off is known as, Gene Regulation. Gene regulation can occur at any point during gene expression, but most commonly occurs at the level of _____, when the information in a gene's DNA is transferred to RNA.

Why can smaller cells diffuse oxygen and nutrients at a faster rate?
small surface area to volume ratio
large surface area to volume ratio
large surface area
more volume than surface area

Answers

Answer:

A further increase in the size of a cell could result in a surface area too small for adequate exchange of materials.: A large surface to volume ratio means that a small amount of living matter has a large surface through which nutrients, oxygen and wastes can diffuse.

Answers

Answer:

Reflex action/reflex arc/reflex (allow "involuntary") The stimulus (heat) is detected by temperature receptors in the skin. This causes impulses to travel along a sensory neurone to the spinal cord, due to chemical changes across the synapses. Here they go along a relay neurone, and then are sent via a motor neurone to the effector (an arm muscle in this case). The muscle contracts, moving the hand away and preventing further harm.

Hypertonic: The cell will shrink because it loses water

Explanation:

Cells use a molecule called (DNA / RNA / ATP / CMP) to store and release energy like a battery. The energy is stored in chemical bonds between (nucleotide / oxygen / phosphate / ribose) groups of the molecule, and the energy is released when the chemical bonds are broken.

Answers

Answer:

Cells use a molecule called ATP to store and release energy like a battery. The energy is stored in chemical bonds between phosphate groups of the molecule, and the energy is released when the chemical bonds are broken.

Explanation:

The Adenosine Triphosphate (ATP) is a molecule made of adenine, ribose, and three phosphate groups, which are the ones that store the energy in its bounds.  The ATP is the molecule that provides the energy to the different processes that happen in a cell. The molecule is made from the glycogen, fats, and carbohydrates that the body has absorbed in the intestines. When the body needs energy, the ATP loses one or two phosphates, becoming ADP and AMP. When the phosphorylation happens, which is the loss of phosphate, the energy is released.

define magnification and cisternae?​

Answers

Answer:

Magnification In general terms, it can be said that how big or small the image appears with respect to the object is called magnification of the object.

Explanation:

It is represented as the ratio of the height of the image to the ratio of the height of the object. Magnification is denoted as the letter 'm'.

Magnification is the process of enlarging the apparent size, not physical size, of something. This enlargement is quantified by a calculated number also called "magnification".

A cisterna refers to a flattened membrane disk that makes up the Golgi apparatus. A typical Golgi has multiple stacks of anywhere from 3 to 7 cisternae stacked upon each other like dinner plates.The cisternae also carry structural proteins important for their maintenance as flattened membranes and their stacking upon each other.

What syndrome does this karyotype show?

Answers

Answer:

C

Explanation:

The karyotype shown in the question is characteristic of Down syndrome, also known as Trisomy 21. Therefore option A is correct.

Down syndrome is a genetic disorder caused by the presence of an extra copy of chromosome 21, resulting in a total of 47 chromosomes instead of the typical 46.

The karyotype reveals three copies of chromosome 21, indicated as 47,XY,+21, which is indicative of Down syndrome in a male individual.

People with Down syndrome may experience developmental delays, intellectual disabilities, and characteristic physical features, such as almond-shaped eyes and a flat facial profile.

The presence of an extra chromosome 21 is the defining genetic abnormality in individuals with Down syndrome.

Therefore option A is correct.

(i)Explain how the binomial names indicate that insects 1 and 2 are more closely related.
(i)Explain how the appearance of the three inswcts suggest that insects 1 and 2 are more closely related.

HELPPP I NEED TO KNOW NOWWWW!!

Answers

Note:

In the attached files you will find the image of the three insects

Answer:

(i) Because they share the same genera, Vespula.

(ii) Because Morphologically, insects 1 and 2 are more alike than insect 3.

Explanation:

(i) Explain how the binomial names indicate that insects 1 and 2 are more closely related.

In taxonomy, many categories are used to aggregate organisms according to their evolutive relationship. These are Domain, Kindom, Clase, Order, Family, Genera, Species, Subspecies. All species might be recognized by their common name and their scientific name, which is more reliable. The binomial names of living beings indicate the scientific name by which the organisms can be recognized. A species scientific name is composed of two parts:

- Generic name or genera: correspond to many species that share common characteristics. In the example, Vespula is the genera

- Specific epithet: useful to identify each species in particular and differentiate organisms that are included in the same superior taxes. In the example, flavopilosa and rufa are the epithets that differentiate one species from the other.

According to this, we might assume that species 1 and 2 are more closely related because they share the same genera: Vespula. This suggests that they share more characteristics in common with each other than with Callicera.

(ii) Explain how the appearance of the three insects suggests that insects 1 and 2 are more closely related.

Morphologically, insects 1 and 2 are more alike than insect 3. Traits such as body shape, pigmentation pattern, antenna, wings, total body size, among others, are very similar in species 1 and 2. On contrary, species 3 is smaller, with a thinner antenna, different pigmentation patterns, different wings size and shape.

In the laboratory, yeast cells are usually grown at a temperature of 25oC. A scientist wanted to determine if yeast cells would reproduce faster or slower when the temperature was dropped to 15oC. The same number of yeast cells were placed in the same medium with the same amount of nutrients. One sample was kept at 25oC and the other one was kept at 15oC. The number of yeast cells was counted every hour for an eighteen hour period.

Answers

Answer:

This question is incomplete, however, it is asking to identify the following variables:

Independent variable: Temperature

Dependent variable: Number of yeast cells

Constants: same amount of nutrients, same number of yeast cells, same medium

Explanation:

- Independent variable is the variable that the experimenter changes or manipulates in order to bring about a measurable effect. In this experiment, the TEMPERATURE at which the yeast are kept is the independent variable.

- Dependent variable is the variable that responds to the changes made to the independent variable. It is the variable that is measured by the experimenter in the experiment. In this case, The NUMBER OF YEAST CELLS was counted, hence, it is the dependent variable.

- Constants are variables that are kept unchanged or same for all groups by the experimenter in order not to influence the experiment's outcome. In this case, the CONSTANTS are: same amount of nutrients, same number of yeast cells, same medium etc.
