what layer of the retina contains photoreceptors?
The rod and cone layer (bacillary layer) contains the inner and outer segments of the rod and cone photoreceptors cells. The pigment epithelium is the most external layer of the retina.
Answer: The rod and cone layer (bacillary layer) contains the inner and outer segments of the rod and cone photo receptors cells. The pigment epithelium is the most external layer of the retina.
Explanation: Neural (inner) layer - consists of photoreceptors, the light detecting cells of the retina. It is located posteriorly and laterally in the eye.
Blind spot, small portion of the visual field of each eye that corresponds to the position of the optic disk (also known as the optic nerve head) within the retina. There are no photoreceptors (i.e., rods or cones) in the optic disk, and, therefore, there is no image detection in this area
This DNA strand consists of eight pairs of nitrogenous bases. How many different sequences of eight bases can you make? Explain how you found your answer.
Answer:
Explanation:
it would be 4 (possible bases) to the power of 8 because you need to multiply 4, eight times for the number of sequences. Therefore, the answer is 65, 536 possible sequences.

What are some benefits of enzyme production in the process of digestion.
Answer:
definition;
enzymes are protein that catalyze speed up the biochemical reactions and are not changed during the reaction . the molecules at which enzyme work are called substrate and enzymes convert them into different molecules called products.
benefits of enzyme in digestion ;
enzyme lower the activation energy in several ways. they may alter the shape of substrate and reduce the requirement of activation energy . enzyme may also lower activation energy by bringing substrate in correct orientation to react . enzyme break down carbohydrates, lipids and proteins which are component of human food .In digestion larger molecules are broken into smaller molecules like amino acids ,simple sugars ,fatty acid ,vitamins ,salts and water to provide to cells. these molecules are a part of larger molecules like protein ,polysaccharids and lipids . enzymes like amylaze, lypase ,salivary amylase, pepsin ; it is a very strong protein digesting enzyme it is released in its inactive form pepsinogen which is converted into pepsin with the help of H-C-L hydrochloric acid it takes part in digestion in stomach

The K-selection reproductive strategy maximizes the survival of offspring
by producing
Ofew offspring with high levels of parental care
Ofew offspring with low levels of parental care
O many offspring with high levels of parental care
Omany offspring with low levels of parental care
Answer:
The K-selection reproductive strategy maximizes the survival of offspring by producing few offspring with high levels of parental care.
Explanation:
Depending on how many offsprings members of a species produce and how much care they invest in them, we can divide species into two categories:
r-organisms. These organisms produce many offspring, sometimes even thousands of them. They live in unpredictable, dangerous environments with a lot of predators. This is why most of their young die. It's important for at least some of them to survive so that they can continue reproducing and keep the species alive. The parents don't invest much care into their young. Some examples of these species are mice, rabbits, weeds, and bacteria.K-organisms. These organisms are the opposite of r-organisms. They live in more stable environments, which guarantees that their lifespan will be longer. This is why it's not necessary for them to produce many offspring. Parents invest a lot more care into their young. Some examples of these species are humans, elephants, horses, and primates.Based on this information, we can conclude that the K-selection reproductive strategy maximizes the survival of offspring by producing few offspring with high levels of parental care.
Answer:
Answer choice A
Explanation:
Few offspring with high levels of parental care is a characteristics of K-selected species.
What part of DNA determines traits?
Answer:
The traits of a living thing depend on the complex mixture of interacting components inside it. Proteins do much of the chemical work inside cells, so they largely determine what those traits are. But those proteins owe their existence to the DNA (deoxyribonucleic acid), so that is where we must look for the answer.
care of chicks at the age of between 8 to 20 weeks is called ????????
Answer: Brooding
Explanation:
Chicks are kept at high temperature after hatching this process is called brooding.
The chicks require 95-100 degrees temperature for brooding they are not allowed to mix with the flocks until 20 weeks after their birth.
Until this time the chicks learn to eat and drink water.
Overheated chicks can dehydrate and they grow slowly.
