based on the text how would you define a dominant gene what about a recessive gene
Dominant refers to the relationship between two versions of a gene. Individuals receive two versions of each gene, known as alleles, from each parent. If the alleles of a gene are different, one allele will be expressed; it is the dominant gene. The effect of the other allele, called recessive, is masked.
33. Why is it beneficial that plants have two kinds of chlorophyll (a and b)?
Answer:
chlorophyll in plants complement each other in absorbing sunlight.
Explanation:
light with a wavelength of 460 nm isn't always substantially absorbed by means of chlorophyll a, but will as a substitute be captured through chlorophyll b, which absorbs strongly at that wavelength. the two forms of chlorophyll in flowers
It is beneficial to have two kinds of chlorophyll in photosynthetic plants because both types of chlorophyll work complementary to each other and allow maximum absorption of light in the blue to red spectrum.
What do you mean by Chlorophyll?Chlorophyll may be defined as the green-colored pigment in plants, algae, and cyanobacteria that is essential for photosynthesis.
Chlorophyll A absorbs the light of wavelength 400 to 450nm with maximum intensity and 650 to 700nm with minimum intensity.
Chlorophyll B absorbs the light of wavelength 450 to 500nm with maximum intensity and 600 to 650nm with minimum intensity.
Therefore, it is beneficial to have two kinds of chlorophyll in photosynthetic plants because both types of chlorophyll work complementary to each other and allow maximum absorption of light in the blue to red spectrum.

What is the role of cells in vision?Two types of specialized cells are found in the eye for vision. These are named as rods and cones. These cells are called as photoreceptors as they are sensitive to light and thus functions in response to light.
Rod cells function in response to dim light and thus are active during the night time whereas cone cells impart colour vision.
These photoreceptor cells detect the light and convert them into electrical signals. Such electric signals travel to the brain from the retina through optic nerve. Brain thus helps in the perception of objects.
Defects in the rod cells leads to night blindness. It is also due to the deficiency for vitamin A which is pre-requisite for the activation of rod cells. Colour blindness (inability to distinguish between primary colours) can result if the cone cells are damaged.
Thus, photoreceptors cells are important in vision and image formation.

Answer:

Explanation:
The movement of materials from the plasma membrane, through endosomes, and then to lysosomes describes which type of pathway?.
Answer:
Below
Explanation:
The routes that lead inward from the cell surface to lysosomes start with the process of endocytosis, by which cells take up macromolecules, particulate substances, and, in specialized cases, even other cells. In this process, the material to be ingested is progressively enclosed by a small portion of the plasma membrane, which first invaginates and then pinches off to form an endocytic vesicle containing the ingested substance or particle. Two main types of endocytosis are distinguished on the basis of the size of the endocytic vesicles formed. One type is called phagocytosis (“cellular eating”), which involves the ingestion of large particles, such as microorganisms or dead cells via large vesicles called phagosomes (generally >250 nm in diameter). The other type is pinocytosis (“cellular drinking”), which involves the ingestion of fluid and solutes via small pinocytic vesicles (about 100 nm in diameter). Most eucaryotic cells are continually ingesting fluid and solutes by pinocytosis; large particles are most efficiently ingested by specialized phagocytic cells.

10.A 600 kg great white shark is lurking below an observation cage. His movement is
being studied from a series of motion sensors below the boat. The shark leisurely
charges the cage, strikes it and makes the cage rattle. Later, the shark returns for
another run at the cage. The shark strikes the cage with 12,800 N of force. The
shark traveled for 10 m in making its run. The cage is designed to withstand
124,500 J of "work" before it breaks. Should the man in the cage be worried?
Explain.
The work done by the shark is 128000 J which is greater than the maximum force the cage can withstand (124500 J), the man in the cage should be worried.
What is work done?Work done is the product of force and the distance covered by the force.
Mathematically;
Work done = Force × distanceThe unit of work done is Joules.
The work done by the shark is calculated as follows:
Work done = 12800 × 10
Work done = 128000 J
Maximum force the can withstand = 124500 J
Since the work done by the shark is greater than the maximum force the cage can withstand, the man in th cage should be worried.
