According to thw big bang theory of the orgin of the universe the universe has expanded from a hot dense state into a vast, cooler state. What would be considered scientific evidence supporting this theory

Answers

Answer 1

Answer: The scientific evidence is that the distant galaxies are moving away from us at a very high speed. This gives us an idea that the universe was once joint and suddenly exploded after the big bang and started to expand at a speed faster than light.

Which of the following are most responsible for the success of the cane toad as an invasive species in Australia?A) venom glands and varied diet

B) varied diet and prolific reproduction

C) prolific reproduction and strong hind legs

D) strong hind legs and venom glands

Answers

The right option is A) venom glands and varied diet

The venom glands and varied diet are most responsible for the success of the cane toad as an invasive species in Australia.

The cane toad is a big terrestrial toad usually used as pest control against the cane beetle. The cane toads have a toxic skin and venom glands behind their eyes that secrete toxins. The toxins kill animals when it is ingested. The cane toads also have a varied diet. They consume various types of materials such as household garbage, plants in addition to the usual preys of reptiles and birds.

A
The venom glands on the toads prevent them from being successfully predated upon and their varying diet allows them to sustain themselves in diverse environments

Different modes of primate locomotion (7) encompass: a) Bipedalism, quadrupedalism, brachiation, leaping, galloping, swimming, flying b) Crawling, sliding, gliding, hopping, swinging, scuttling, slithering c) Walking, running, hopping, climbing, flying, swimming, burrowing d) Trotting, jumping, floating, wading, rolling, slinking, hopping

Answers

Final answer:

Primates, including humans, have different modes of locomotion such as bipedalism and brachiation due to specific morphological adaptations. These changes have been hypothesized to have evolved from our arboreal ancestors. Each primate subgroup, from lemurs to humans, has adapted in different ways to their environment.

Explanation:

Different modes of primate locomotion includes a series of movements like bipedalism, quadrupedalism, brachiation (swinging from branch to branch), leaping, and more. These locomotion modes are possible due to several morphological adaptations such as a rotating shoulder joint and thumbs and big toe widely separated from other digits, which allow for gripping branches. For instance, in bipedal locomotion, one leg is on the ground (stance leg) and the other is in the air (step leg) striding forward.

All primate species are believed to have descended from arboreal ancestors hence the adaptations for climbing trees. However, not all primate species today are arboreal. Large brains, stereoscopic vision, and a flattened nail instead of claws are among the specific characteristics of primates, especially those adapted to arboreal life.

Interestingly, humans are part of the primate order, which also includes lemurs, monkeys, and apes. These primate groups possess the necessary physical adaptations for different modes of locomotion, which allow them to live in diverse environments from tropical forests to savannahs.

These are folds in the mitochondria that contain enzymes important to ATP production and also increase the surface area for ATP production.

Answers

Answer:

The correct answer will be-true

Explanation:

Mitochondria is a double membrane-bound organelle which is involved in the production of the energy molecules called ATP.

For the production and increase the productivity of the ATP molecules, the cell has modified the mitochondria by making the changes in the inner surface of the organelle.

The inner membrane possesses the enzyme called ATP synthase which synthesizes the enzymes. The inner membrane increases the infoldings called cristae which increases the surface area for the ATP production.

Thus, true is the correct answer.

The folds of membrane are called the cristae, and the inner part ("maze") is called the matrix.

Which genetically engineered medicine is injected into the body to protect a person from the effects of a virus? insulin
the flu vaccine
the human growth hormone
penicillin

Answers

Correct answer: B). The flu vaccine

The flu vaccine is a type of vaccine that protects the body against the flu. It develops antibodies after two weeks of vaccination. These antibodies provide protection against influenza viruses. The flu vaccine reduces the risk of flu illnesses, hospitalization, and flu-related death. It only protects the body against influenza, not any other illnesses.

Hence, the correct answer would be option B.

Answer:
B. the flu vaccine

A change in a sequence of DNA bases in a bacterial cell has resulted in a mutation. This mutation has increased the ability of the bacteria to break down and digest organic molecules in the environment. Bacteria with this mutation are better able to find and utilize food sources. According to the theory of natural selection, what is MOST likely to occur in future generations of this bacteria?A)The relative frequency of the mutation will increase as time passes. B)Because the mutation has changed the DNA of the bacteria, a new species will be formed. C)Because the mutation is abnormal, the mutation will become more rare with every passing generation. D)Bacteria with the mutation will increase in number until the food supply is exhausted, causing the bacteria to become extinct.
