How do transitional fossils help explain the evolutionary steps that took place to produce modem organisms?
Answers
Answer:
Transitional fossils show how a particular taxa accumulated adaptations to fit particular environments and/or ecological niches
Explanation:
Transitional fossils are fossilized remains of taxonomic groups/species that illustrate an evolutionary transition between a known version of a taxa/species and the current taxa/species. Transitional fossils are fundamental because they can be clearly differentiated from the ancestral group as well as of its derived descendant group. For example, there exist transitional fossils known as "mammal-like reptiles"(i.e., therapsids that gave rise to the true mammals), which are clearly different from current mammals.

Osmolarity tells you the concentration of solute particles in solution, osmolarity cannot always tell you the direction of water movement across a membrane.
a. True
b. False
Answers
Answer:
a. True
Explanation:
Osmolarity is a measure of solute concentration, that is, it indicates how much solute there is in a liquid. As we know, osmosis is the movement of solute across the cell membrane, where the solute passes from the more concentrated side to the less concentrated side. Osmolarity is directly linked to this concept, but it is not able to indicate the direction of movement of the solute. This is because the solute will only pass through the membrane if it is a penetrating solute. Non-penetrating solutes do not have the ability to move through the membrane, even though the osmolarity of the liquid is high.
The growth of the human population directly relates to the use of natural resources by humans. Based on the graph, which two statements about human use if natural resources are most likely true?
A. resources use by humans will be higher in 20 years than it is now
B. resource used by humans is much higher now than it was 200 years ago
C. Resource used by humans in steadily decreasing over time
D. Resource used by humans is about the same now as it was 150 years ago
Answers
Answer:
A. resources use by humans will be higher in 20 years than it is now
B. resource used by humans is much higher now than it was 200 years ago
Explanation:
The growth of the human population has direct relation with the use of natural resources by humans means if the population of humans increases, more natural resources will be consumed by the population. Directly relation means if one increases the other automatically and vice versa. more population needs more resources for their growth and survival so we can conclude that resources used by humans will be increases if the population increases.

When crossing a true breeding white mouse with a true breeding brown mouse your friend tells you she recovered all black mice. But then when she crosses the F1 mice to each other she recovered 28 black mice, 8 brown mice, and 13 white mice. Can you help her explain these results? (Type out the cross and include genotypes of as many mice as possible. What phrase best describes this phenomenon? How many genes are involved are they linked or unlinked? Etc.)
Answers
Answer:
Following are the response to the given question:
Explanation:
[tex]White = aaBB \\\\Brown = AAbb\\\\Parental \ \ cross: aaBB \times AAbb\\\\F1 \ progeny: AaBb\\\\F1 \ selfing: AaBb \times AaBb\\\\F2 \ progeny:\\\\[/tex]
[tex]\frac{9}{16} = A_{B_} = Black\\\\[/tex]
[tex]\frac{3}{16} = aaB_ \ = White\\\\[/tex]
[tex]\frac{3}{16} = A_{bb} = Brown\\\\\frac{1}{16} = aabb = White\\\\[/tex]
The observed progeny ratios closely match the morphological ratio of 9:3:4. That's a hereditary pharmacogenetic example.

There are both membrane-bound and non-membrane-bound organelles in these cell organelles, which are found within the cells and have distinct structures and functions. The direction and capability productively for the ordinary working of the cell.
Depending on whether or not they have a membrane, the various organelles that are found within the cell are divided into three groups. The types are double membranes, single membranes, and no membrane organelles.

The work below shows the steps he used.

What error did Luke make?
O He forgot to put the numbers in order first.
O He crossed off the low and high pairs incorrectly.
O He left out a number when putting the numbers in
order.
O He did not make an error.
16 + 22 = 38
2 2
16 22 = 38
19
Answers
Answer:
He left out a number when putting the numbers in order.
Explanation:
To find the median of a set of numbers, first arrange the numbers in order from least to greatest. Then begin crossing numbers of from each side at the same time.
Luke did not cross numbers off from each side, but only crossed them off from the left side. He also skipped a number, given there are only 2 "X's."
The list should look like so:
7, 11, 12, 16, 22, 24, 30
There should be three numbers before 16, not two as he has listed.

Answers
Answer:
a. nails are a scalelike modification of the stratum corneum layer of the epidermis
b. nails form on the dorsal edges of the fingers and toes
c. fingernails do protect the digits from damage
Explanation:
The stratum corneum consists of the top layer of the epidermis (i.e., skin). Nails represent a modification of the epidermis and they are composed of densely packed dead skin cells (keratinocytes), which are rich in a protective protein called alpha-keratin. The nail plate is the hard keratinized part of the nail. The nail bed is the skin underneath the nail plate. The nails grow from the proximal portion of the nail bed, which is known as the nail matrix. The main function of the nails is to protect the tips of fingers and toes from injury.
The predatory bacterium Bdellovibrio bacteriovorus is able to penetrate a gram-negative bacterium that has a slimy cell covering. What is the correct sequence of structures penetrated by B. bacteriovorus on its way to the prey's cytoplasm
Answers
Answer:
The order of bacterial structures that the bacteria would penetrate would be:
Capsule.Lipopolysaccharide MembranepeptidoglycanPhospholipids Membrane.Explanation:
A parasite like B. bacteriovorus faces some challenges in getting into a bacterial cell. This is because these cells have devices and strategies to prevent the entry of parasites and ensure the survival of the bacteria. The first challenge would be to penetrate the bacterial capsule. The capsule is a structure that is located around many bacteria. This structure is rigid, with sharp edges and thick thickness, which protects the bacteria from external agents. If B. bacteriovorus manages to go beyond the capsule, it will find a membrane, also thick, composed mainly of lipopolysaccharides, which will also provide protection and try to prevent the entry of the parasite. If this membrane is crossed, B. bacteriovorus will face another layer called peptidoglycan. This layer establishes itself as a cell wall, being very difficult to break. Some bacteria present one more layer after peptidoglycan, which is a membrane made by Phospholipids, which is highly selective and difficult to break, but is more fragile than the previous layers. Only after overcoming all these structures, the parasite will have access to the bacterial cel
