Gigantic mammals (mammoths, giant sloths, etc.) characterize these times.a. Pleistocene,
b. Holocene,
c. Pliocene,
d. Cretaceous

Answers

The answer is a. Pleistocene.

A group of large animals that lived during the Pleistocene is called Pleistocene megafauna. This group included mammoths, giant sloths, mastodons, cave bears, saber-toothed cats, etc. The extinction of these animals happened also in Pleistocene. The reasons for their extinction could be hunting by the humans, climate changes, or impact of asteroides.

What is intramembranous ossification? the formation of bone from preexisting hyaline cartilage models
the formation of bone from preexisting elastic cartilage models
the formation of bone from preexisting fibrocartilage models
the formation of bone from fibrous membranes

Answers

Answer is (D)

Explanation:

  • Intramembranous Ossification is the procedure in which development of bones from fibrous membranes.
  • It is engaged with the development of the mandibles,the clavicles and the level bones of the skull.
  • Hardening starts as mesenchymal cells structure a layout of things to come bone.
  • They at that point separate into osteoblasts at the hardening community.
  • Osteoblasts emit the extracellular framework and store calcium, which solidifies the network.

Infer whether species diversity increases or decreases after a fire on a grassland. explain your response.

Answers

Answer:

Decreases.

Explanation:

Biodiversity may be defined as the variety of the living organism found in the earth. The diversity of the species may get affected and do not have any constant number.

The natural or human made calamity can decrease the species diversity. The fire on a grassland causes the death of many species, have harmful effects on many species and reduces the species number as well. This decreases the species diversity of the grassland.

Thus, the answer is decreases.
Due to a natual disaster many animals are likely to die. However animals with mutations would be more likely to survive than others. These animals that survive can now pass on their to their offspring. Thus contibuting to evolution. In conclution it increases species diversity

In human DNA, adenine (A) makes up approximately 30.9% of the bases, andguanine (G) makes up approximately 19.9% of the bases; therefore the percentage thymine (T) and cytosine (C) are
(A) 19.8% T and 19.8% C.
(B) 19.8% T and 29.4% C.
(C) 29.4% T and 19.8% C.
(D) 29.8% T and 29.8% C.
(E) 19.9% T and 30.9% C.
Can you please explain with some details?

Answers

In human DNA, there are nitrogenous base pairings- A, T C and G. A pairs with T and C pairs with G. Because they're a pair, the ratio of A:T and C:G should be as close to 1:1 as possible. Since A makes up approx 30.9%, T should be either C or D. As G makes up approx 19.9%, we can rule out option D, therefore the answer is C! Hope this helps (:

Surface tension is caused by cohesion (the attraction of molecules to like molecules). Since the molecules on the surface of the liquid are not surrounded by like molecules on all sides, they are more attracted to their neighbors on the surface.

Diuretics, which are also called "water pills," are used to treat a variety of medical conditions. One of the side effects of diuretics is frequent urination, as water is removed from blood and excreted in urine. Which of the following best explains how blood pressure would be affected by diuretics?A It would decrease as blood volume decreases, making it easier for the heart to pump blood.B It would decrease as the kidneys work harder to add water to the blood.C It would increase as the kidneys work harder to counteract the diuretic's effect.D It would increase as blood volume increases, making up for the body's loss of water.
