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!
Answer:
(A) Benthic- Benthic refers to the lowest or the bottom zone of the water body such as seas, and oceans. The organisms existing under such extreme pressure conditions are commonly known as benthic organisms. For example, corals and bivalves.
(B) Pelagic- Pelagic refers to the upper top portion of a water body, covering the open sea areas. The organisms existing in this region include dolphins and sharks.
(C) Sessile- Sessile refers to the property where an organism is stationary and cannot move freely from one place to another. These are known as sessile organisms such as coral polyps, Mussels.
(B) Mobile- refers to the property by which an organism can move freely in any direction it wants. For example, fishes, dolphins.
(E) Evisceration- It is a specific type of property where organisms can eject their internal organs in order to protect themselves from predators. for example, Sea cucumbers.
(F) Chitin- Chitin is a hard shell that is present in various organisms, forming its exoskeleton, for defense purposes. For example, arthropods.
Answer:
1. Cinder cones
2. All of these
Explanation:
1. Cinder cones develop from explosive eruptions of mafic (heavy, dark ferromagnesian) and intermediate lavas and are often found along the flanks of shield volcanoes. The outside of the cone is often inclined at about 30°, the angle of repose (the slope at which the loose cinder can stand in equilibrium).
2. Volcanic Explosivity Index (VEI) is a numeric scale that measures the relative explosivity of historic eruptions. Volume of products, eruption cloud height, and qualitative observations (using terms ranging from "gentle" to "mega-colossal") are used to determine the explosivity value. The Volcanic Explosivity Index (VEI) was derived to catalogue the explosive magnitude of historical eruptions, based on the order of magnitude of erupted mass, and gives a general indication as to the height the eruptive column reached.
Hope this helps!
Which of these values would most likely be the heritability of body mass index (BMI) in a developing country with a large gap between nutrition and health care available to the rich and poor?
a. 0.33
b. -0.88
c. 0.99
d. 0.0001
e. 1.3
Answer:
a. 0.33
Explanation:
Body Mass Index is defined as the measure of fat depending on the height and weight of individuals. It is being calculated as: BMI=
The most likely heritability of body mass index(BMI) in a developing country with a large gap between nutrition and health care will be 0.33.
These is because in developing countries especially countries experiencing rapid economic growth as illustrated by the annual GDP growth rate are likely to have widely ranging lifestyles due to influences of the burgeoning economy, Therefore, there are greater chances for the rich to have access to the basic requirements and necessities of life whereas the poor are limited with either low or no access to adequate nutrition and health care.
