. polarity in the developing drosophila embryo is determined by____

Answer:

Question 13:

B. False

The most abundant photoreceptors that detect dim light are Rods, not Cones. Rods are highly sensitive to low light conditions and are responsible for vision in dim light and peripheral vision. Cones, on the other hand, are responsible for color vision and high visual acuity but are less sensitive to low light conditions.

Question 14:

A. True

The iris is the muscular tissue in the eye that adjusts the size of the pupil, controlling the amount of light entering the eye. It contracts or expands to regulate the size of the pupil in response to changing light conditions.

Question 15:

B. False

Opsins are visual pigments found in photoreceptor cells, specifically in the retina of the eye. They are responsible for capturing light and initiating the process of vision. Opsins are not derived from Vitamin D. Vitamin D is a separate compound involved in various physiological processes in the body, including calcium absorption and bone health.

Answer:

oxidation of carbohydrates obtained from food.

Answer:

Some integral membrane proteins are responsible for cell adhesion (sticking of a cell to another cell or surface). On the outside of cell membranes and attached to some of the proteins are carbohydrate chains that act as labels that identify the cell type.

The β-oxidation pathway is a metabolic process that takes place in the mitochondria of cells and involves the breakdown of fatty acids into smaller molecules such as acetyl-CoA.

It is composed of four steps: coenzyme A activation of the fatty acid, acetyl-CoA cleavage into two-carbon and four-carbon molecules, and subsequent breakdown of the four-carbon molecule into two-carbon molecules.

These actions cause ATP, which is energy, to be released. In contrast to liver, muscle and adipose tissue employ -oxidation differently.

Fatty acids are converted into ATP and used as a source of energy in muscle. Fatty acids are used to store energy in adipose tissue.

Fatty acids are broken down and digested in the liver to create ketone bodies, which can be used as an energy source by other organs.

Miller and Urey experiment tried to recreate the primitive atmospheric conditions earth had when it was completely abiotic (deovid of any form of life). Their results, showed that with the putative composition of inorganic compounds, plus a source of energy (like lighting) the emergence of organic compounds was likely. With this result, it was suggested that after millions of years of interacting organic molecules (olds and new ones) lipids and proteins would eventually arise. This experiment is not perfect, and has many assumptions (potentially drawbacks), but showed that organic compounds (the chemical basis of life) could emerge from quite simple components.

The biotechnology cluster deals with the scientific aspect of agriculture modification, while the power, structural, and technical systems cluster deals with the logistical aspects of farm planning and maintenance. Thus option 2 is correct.

What Is Biotechnology?

Biotechnology is an applied science with technological application.

It is the science-driven industry which is quite different from pharmaceutical industry as it is completely based on living organisms and molecular biology work to provide solution from human healthcare to agriculture field.

It has a role in DNA fingerprinting, medicine, genomics, production of food and biofuels.

It is a combinational study of application of biology, physics, chemistry, mathematics, science, and technology.

Answer:

Because the moon is closer to Earth than the sun, that is to say, the gravitational pull of the moon is stronger than the gravitational pull of the sun affecting the tides more than the sun.

Explanation:

The sun has a larger size than the moon and stronger gravitation. However, as it is farther from the Earth in comparison with the moon, the gravitational pull between the sun and our planet is weaker than the one between the moon and the Earth. Even though the moon is smaller, the gravitational pull is stronger because it is closer to Earth. As a result, the moon affects the tides more than the sun does.

The cell that is not a phagocytic cell is the Basophil. Macrophages, Monocytes, and Neutrophils are all phagocytic cells involved in the immune response. So, the correct answer is option d.

Phagocytic cells are specialized cells in the immune system that are responsible for engulfing and destroying foreign particles, such as bacteria and viruses. Macrophages are large phagocytic cells that are found in tissues throughout the body. Monocytes are white blood cells that can differentiate into macrophages or dendritic cells. Neutrophils are the most abundant type of white blood cell and are the first responders to infection.

Basophils, on the other hand, are not phagocytic cells. They are a type of white blood cell that plays a role in allergic reactions by releasing histamine. Basophils are also involved in the immune response by signaling to other cells to initiate the inflammatory response.

Most of the rocks and minerals that make up the Earth's crust are composed of cations and anions held together by ionic bonds. Ionic compounds are electrically neutral compounds consisting of cations and anions. I am familiar with some ionic compounds such as sodium chloride.

A covalent bond is a force that attracts two atoms sharing a pair of valence electrons. Shared electrons are attracted to both nuclei. This creates a  dipeptide molecule made up of two or more atoms.

Explanation:

Most autotrophs make their "food" through photosynthesis using the energy of the sun. Heterotrophs cannot make their own food, so they must eat or absorb it.

The process that occurs only in autotrophs and never in heterotrophs is photosynthesis. The correct option is D.

Autotrophs are organisms that produce their own food, which means they do not need to hunt or look for food, such as plants.

Heterotrophs are animals that are unable to produce their own nutrients, so they must rely on an external source of energy, which they obtain through hunting, scavenging, and other means.

Photosynthesis only occurs in autotrophs, as they produce their own food through this process. Most autotrophs obtain their "food" by using the energy of the sun via photosynthesis. Heterotrophs are unable to produce their own food, thus they must consume it or absorb it.

By people stepping on the little bugs, it kills them. and when they are born some will die and others won't

Explanation:

The cartoon refers to the principle of natural selection, which operates in many species, including bugs.

When individuals of a species reproduce, their offspring inherit certain traits or characteristics that can be advantageous or disadvantageous. In the case of bugs, some may have stronger exoskeletons, faster reflexes, or better camouflage, which can help them survive being stepped on or avoid being noticed by predators.

As a result, those bugs with advantageous traits are more likely to survive and reproduce, passing on their favourable characteristics to the next generation, while those without these traits are more likely to die. This is an example of natural selction.
