Answer:true
Explanation:The function of the plicae circulares, the villi, and the microvilli is to increase the amount of surface area available for the absorption of nutrients. Each villus transports nutrients to a network of capillaries and fine lymphatic vessels called lacteals close to its surface.
Calculate the force needed to cause a 6 kg bowling ball to accelerate 20 m/s2.
Answer:
Explanation:
F = m * a
m = 6 kg
a = 20 m/s^2
F = 6 * 20
F = 120 N which is short for Newtons.
Describe limits to cell division.
Answer:
All cells in the body have this internal control and most cells only divide between 50-70 times before they stop or die.
The study of cells is called cell biology.
The cell theory is given by Rudolf Virchow
The postulates of a cell theory are as follows:-
All the organism is made up of cellThe structure and the functional unit of life is the cell.All the pre-existing cell is made up of old cell.The limits of the cell division are cancer cells. The cancer cell does not stop after a limit. It divides continuously and forms a tumor.
Hence, the correct answer is a cancer cell.

how do mutations and natural selection lead to resistant populations of bacteria
Answer:
Mutations are one way for bacteria to become resistant to antibiotics. Some spontaneous mutations (or genes that have been acquired from other bacteria through horizontal gene transfer) may make the bacterium resistant to an antibiotic (See: Resistance mechanisms for information about how bacteria resist antibiotic action). If we were to treat the bacterial population with that specific antibiotic, only the resistant bacteria will be able to multiply; the antibiotic selects for them. These bacteria can now increase in numbers and the end result is a population of mainly resistant bacteria.

Why do you think ANIMAL CELLS are able to survive without the types of cell walls that are present in nearly every other group of organisms? Provide 3 answers.
Answer:
They survive because these cells need a high permeability to be able to maintain the internal cellular balance in relation to the external environment that surrounds them, and this is due to their high energy demand, their multi-complex and multiple functions, and the capacity for constant homeostasis with the environment. that surrounds them.
Explanation:
In addition, some cells need to transmit signals, second messengers or even to fulfill a function to exchange compounds for their transmembrane, this is what makes the human system together with other systems of other animals is extremely open and is in constant energetic exchange, in addition to Unlike plant cells, plant cells are under an autonomous regime, they do not need to take energy from the environment but they manufacture it themselves, and it fulfills a great function that is to provide structure and support, the wall they have is what gives it the ability to fulfill these two functions.

If a cell in G1 has 20 chromosomes, then at the end of meiosis I there will be _________ chromosomes in each daughter cell, and __________ sister chromatids in each daughter cell.
Answer:
10 chromosomes
20 chromatids
Explanation:
Meiosis is the process by which sexually reproducing organisms produce gametes for sexual reproduction. Meiosis, which reduces the chromosomal number of the parent cell by half, occurs in two stages namely: meiosis I and meiosis II.
Meiosis I is where the actual reduction in chromosomal number takes place because homologous chromosomes are separated in this stage. For example, a cell in G1 that has 20 chromosomes will have 10 chromosomes in each daughter cell at the end of meiosis I.
Since, DNA replication occurs in the S-phase, sister chromatids are formed for each chromosome. Hence, there would be 20 sister chromatids joined together by a centromere at the end of meiosis I.
If there is a logarithmic relationship between stimulus intensity and action potential frequency in sensory neurons, how much will the action potential rate increase if the stimulus intensity increases by 100?
Answer:
The action potential rate will be doubled
Explanation:
The logarithm of a number for a given base is the power to which the base must be raised to give the number. Logarithm of a number can be in different bases. The base of common logarithm is the base 10.
For example, logarithm of 1000 to base 10 is 3 because 10 raised to power 3 equals 1000
Log₁₀1000 = 3 since 10³ = 1000
Therefore, if there is a logarithmic relationship between stimulus intensity and action potential frequency in sensory neurons and the stimulus intensity increases by 100, the action potential rate will increase thus:
Log₁₀100 = 2
Therefore, the action potential rate will be doubled

In lab this week we observed a frog dissection. I love the frog dissection because many of the frog's organs look very similar to a human's organs! Let's think back to the frog's digestive system. The frog's digestive system is very similar to a human's digestive system, but not exactly the same. For your post, imagine that a frog eats a fly. Write the path the fly would take through the frog's digestive system, starting with the mouth and ending with the cloacal opening.
Answer:
Mouth, esophagus, stomach, small intestine and large intestine.
Explanation:
Digestive system of frog starts in the mouth and ends at the cloaca which means the enzymes present in the mouth start break down of food eaten by the frog. After food enters the mouth, it goes to the esophagus and then to the stomach. From there, it forwarded to the small intestine, where food becomes broken down and all nutrients extracted from it. it then goes to the large intestine, which absorbs remaining water.
