Answer:
a. autotriploid of species A: 63 chromosomes
b. autotetraploid of species B: 96 chromosomes
c. allotriploid from species A and B: 1) 66 chromosomes and 2) 69 chromosomes
Explanation:
<u>For a.</u>
this species will have 3 haploid sets of chromosomes ('tri' means 3)
one haploid set = 21
21 × 3 = 63 chromosomes
<u>For b.</u>
this species will have 4 haploid sets of chromosomes ('tetra' means 4)
one haploid set = 24
24 × 4 = 96 chromosomes
<u>For c.</u>
there are two ways to do this:
1) two sets of chromosomes from species A and one from species B
42 + 24 = 66 chromosomes
2) one set of chromosomes from species A and two from species B
21 + 48 = 69 chromosomes
Hope that answers the question, have a great day!
Rinderpest disease is caused by a virus that affects hoofed animals, including cattle and wildebeest. In the 1950s, a cattle vaccination program was implemented to eradicate the disease in the Serengeti, and this led to dramatic changes in the populations of wildebeest and other species. The figure shows the number of wildebeest in the Serengeti ecosystem (shaded circles, left y-axis) and the prevalence (i.e., percentage) of individuals infected by rinderpest disease (unshaded squares and triangles, right y-axis) from 1958 to 2003.
The correct answer is Solid.
the source of the filtrate is Loop of Henle.
The Henle loop is surrounded by tissue fluid with a high ion concentration. Osmosis causes water to move out of the descending limb. As a result of the more concentrated filtrate, ions move out of the loop in the thin ascending limb.
The nephron consists of a single long tubule and a ball of capillaries called the glomerulus. Using hydrostatic pressure, plasma is forced through the walls of the glomerulus, becoming filtrate as it crosses, and then collecting within Bowman's capsule. The fluid that enters vertebrate nephrons is called the filtrate.
<h3>Which part of the nephron is called the loop of Henle?</h3>
A million nephrons are the filtering units of the human kidney, which is a complex and highly vascular organ. Each filters water and solutes from the blood that flows through it into the surrounding space and is the cavity between the cup's walls. The other part resembles a U-shaped loop that transports the filtered fluid deep into the medulla.
<h3>Functions of Nephron</h3>
The primary function of the Nephron is to flush out waste products from the blood, which include solid waste and other excesses. This blood is transformed into urine through secretion and excretion.
The nephron, a basic structural unit of the kidney, is a microscopic structure composed of a renal corpuscle and a renal tubule.
