d. domestic animals.

Answers

Answer 1
Answer:

Answer:

C. Placental mammals

Explanation:

The placentals are the largest group of mammals, totally dominating the class and terrestrial habitats.

Amnium, the fluid that protects the embryo from adhesions and shocks, is installed in the female's uterus for development with the help of a placenta that provides fixation and nutrients.

This breeding method, although producing a smaller number of offspring per pregnancy, has a high success rate, allowing greater chances of survival to offspring.

The tip of the tongue in a live frog is sticky. What would be the advantage to this?

Answers

The advantage of the tip of the frog’s tongue being sticky is that it can catch insects very easilyeven if they fly very fast such as the fly. The long length of the small intestine relates to its function in absorbing digested food because ittakes more time to pass through and allows for more calories and nutrients to be absorbed. In the frog’s heart the ventricle has a thicker wall than the atrium because it pumps bloodthroughout the body and to the lungs. The atrium only receives blood and then pumps it into theventricle.

From your knowledge about the distribution of electrons in their shells and from the atomic number (in parentheses), indicate the most likely charge on the ion when this atom forms an ion. (Remember the 2-8-18 shell distribution.) Hydrogen (1)

Answers

The right answer is C. +1 (for hydrogen).

The hydrogen atom can lose its single electron to give the H + ion, commonly referred to as the proton name. In fact, the atom which has lost its only electron is reduced to its nucleus, and in the case of the most abundant isotope 1H, this nucleus consists only of a proton. This name is not strictly correct if one takes into account the presence, although discrete (less than 0.02%), of the other isotopes. The name hydron is more general (we also say hydrogen ion, despite the possible confusion with the H- anion).

Answer:

C. +1 (for hydrogen).

Which feature is found most often in prokaryotic cells?A) plasmid
B) flagella
C) cytoplasm
D) cell membrane

Answers

I would go with the plasmid because the covering is made of it
If we're saying found more often in prokaryotic versus eukaryotic cells, the answer would probably be flagella. Eukaryotic and prokaryotic cells all have cytoplasm and cell membranes at the very least, and its more common in prokaryotic but eukaryotic cells could also have plasmids. Flagella could be occurrent in eukaryotic cells as well, particular in unicellular organisms like protists and even sperm cells, but that feature is probably more common with prokaryotic cells out of all the options in the list.
