Answer:
b) Produce and store large numbers of white blood cells
Explanation:
The lymphatic system's primary role is to produce white blood cells. The main organs were these cells are produced are the bone marrow, the thymus, the spleen, and the lymph nodes, which are distributed in different parts of the body, such as our neck, armpits and near the groin. these organs produce and store white blood cells, that will circulate in the blood or will be in action when the blood is filtered in the spleen or lymphatic nodes.
The answer is Corpus callosum. The largest structure of the human brain, consisting of the two cerebral hemispheres connected by the corpus callosum and covered by the cerebral cortex. Corpus callosum is a long, thick band of nerve fibers that connects the left and right hemispheres of the brain and allows communication between them. Development of the CC makes communication between the hemispheres more efficient.
Answer:
20.3%
Explanation:
Given that:
An AAbb strain is crossed to an aaBB strain
i.e.
AAbb × aaBB
gametes Ab aB
For F₁
generation;
If the resulting progeny are now self-crossed.
We know that the genetic distance between these two genes on the same chromosome is said to be 10 cM.
i.e. the recombinant gene = 10%; Hence, the parental gene will be (100 - 10)% = 90%
Ab × aB = Aa AB ab Bb
From above; the parental gene;
Ab and aB = 90% with each being 45%
i.e. Ab = 45% and aB = 45%
while the recombinants genes are:
AB and ab = 10%
i.e. AB = 5% and ab = 5%
Finally; the percentage of aaBB is = aB% × aB% × 100%
the percentage of aaBB is = 0.45 × 0.45 × 100%
the percentage of aaBB is = 20.25% ≅ 20.3%
The axons of the olfactory sensory neurons project to the olfactory bulb in the brain. This part is found in the forbrain and is responsible for the sense of smell. Inside this bulb are spheres of tissue that are called glomeruli. They are from the ends of branching axons.
The answer is sea stars. Sea stars can then push their stomachs out of the body while inserting it into the prey thus the food is being digested externally. Echinoderms are having 5 or at times multiple of 5 arms. Their shell is made of calcium carbonate.
