Answer:

The immature prefrontal cortex lead to  conflict for teens because the teenagers when they try to use the frontal lobe for reasoning, they tend to overdo it and then giving their brain much work to do. This leads to conflict in teens.

Explanation:

In teens, the prefrontal cortex is immature and develops until the mid-20s of their age. It covers the front part of the frontal lobe. As a result of the immaturity of the prefrontal cortex in teens, they do not think or make decisions like that of adults. When they try to overdo with their immature prefrontal cortex, they end up in conflicts.

Nitrogen cycle

Explanation:

Nitrogen gives nutrients to the soil

Answer:

C.

Explanation:

Volume, no

Milliliters , no

Surface Ratio, come on

The rate of nutrients and waste are exchanged from the cell and the environment depends on surface area to volume ratio.

The amount of square meters of surface area per unit volume is known as surface area to volume ratio.

The surface area to volume ratio becomes smaller as the size of a cell increases.

The exchange takes more time when the surface area to volume ratio is small.

Answer:

mitochondria

Explanation:

aerobic is active and energy is produced in the mitochondria so if the mitochondria was damaged it would affect the active transport

In an aerobic cell, active transport is most directly affected by damage to the - Mitochondria as it provides energy for active movement.

Active transport is a movement of particles through the cell membrane against the gradient, or particles too large to move, therefore, they require additional energy to move such substances.

If mitochondria are damage in a cell there will be no energy formation and as active transport requires energy this process will be affected directly.

Thus, the correct answer is - mitochondria.

Answer:

(B) Products like "Tums" neutralize stomach acid because Tums is a base.

Explanation:

If the product neutralizes an acid, that means it must be a base. Acid + Base = Neutral. If you were to consume an product that is acidic, the stomach will end up being overly acid, which is unsafe for the body. If you were to consume a product that is neutral or "normal", the product would not do as much to neutralize the stomach acid, compared to a more basic pH. Tums has a main ingredient of calcium carbonate, CaCO3, a base. This ingredient helps regulate the pH levels for your stomach so that it does not become too acidic.

Answer:

Competition

Explanation:

Competition occurs when many organisms are in search for the same, limiting resource this include food, water,space.

The use of this limited resource by one species decreases availability to the other population especially when there is an increase in population the rate of competition is very high.

Competition reduces the fitness of all the organism and can either be interspecific which is among the same organisms or between different species.

2. Fossils

Explanation:

1. Rate of southern movement of the plate = 2 cm/year.

In 4000 years, the plate will move a distance of 4000 years * 2 cm/year = 8000 meters

Therefore, the plate will move a distance of 8000 meters south in 4000 years.

2. Wegener in supporting his theory of continental drift used fossils, geologic and glacial evidences. He compared the fossils found in different continents and argued that the presence of fossils of certain animal fossils such as the Lystrosaurus which are found in antarctica, India and South Africa indicates that the continents drifted apart as the Lystrosaurus could not have swam across the ocean to get to these different continents. Also, using geologic evidence by comparing rock structures on opposite sides of the Atlantic ocean, he determined that there were similarities between the rock strata of the Karroo system of South africa with the Santa Carina system in Brazil.

Answer:

A. division of the nucleus

Explanation:

Mitosis is a biological process that the cells of all organisms go through in order to replicate and reproduce. It is part of the cell cycle, which is made up of G1, S, G2, and M (mitosis). In G1, the cell is growing; in S, the DNA of the cell is synthesized, or replicated, so we know choice C is wrong; in G2, the cell is being prepared for mitosis; and finally, in M, the cell actually undergoes cell division.

So, we are looking for an answer choice that involves division: either A or D.

At the end of mitosis, there's an additional process called cytokinesis that actually divides the cytoplasm, so the answer can't be D.

Thus, the answer is A.

Answer:

D = M/V

Explanation:

Density is equal to the mass over volume.

Answer:

1. When DNA is duplicated from mRNA which DNA, mRNA uses a U nucleotide instead of T.

2. If the mRNA sequence is GUACUGUAC, the DNA Sequence is CATGACATG.

Explanation:

1. The only thing that changes from a DNA sequence to an RNA sequence is that the thymine (T) in DNA is changed to Uracil (U) in RNA.

2. There should be no Uracil (U) in a DNA sequence–– only ATCG. Just matching with the given pairings.

G can transcribed to C.

C can be transcribed to G.

A can be transcribed to T.

U can be transcribed to A.

Answer:

Both nuclei has similar shape and size.

Explanation:

The two nuclei are similar in size and appearance which is formed as a result of mitosis. Mitosis is a type of cell division in which a parent cell divides and produces two daughter cells that are identical to each other in size and shape. When the daughter cells formed the parent nuclei is divided and half part of nucleus is present in each daughter cell.

Classifying microorganisms poses a greater challenge compared to higher organisms largely because microorganisms cannot be classified into functional groups based on anatomical characteristics or biological properties.

Classification of living organisms is the process by which living organisms are classified or grouped together based on similarities in structure and function of body parts.

The higher organisms, plants and animals are more easily classified than microorganisms because they not have very similar anatomical or biological characteristics.

In conclusion, classification is the process by which living organisms are placed into classes based in shared features.

The discussion of irf4 transcription-factor-dependent cd103 cd11b dendritic cells drive mucosal t helper 17 cell differentiation is given in the below paragraph-

The predominant migratory DC population in the small intestinal lamina propria (SI-LP) is composed of CD103(+)CD11b(+) dendritic cells (DCs), although it is yet unknown what these cells do in vivo. Here, we show that intestine CD103(+)CD11b(+) DC survival required IRF4 to function (IRF4). Mice with a DC loss in Irf4 showed decreased numbers of helper T 17 (Th17) cells that secrete IL-17 in the gastrointestinal tract and failed to support Th17 cell development in draining mesenteric lymph nodes (MLN) after immunization. Both CD103(+)CD11b(+) MLN DCs and DC-derived IL-6 were selectively decreased in the latter. Immunized Il6(-/-) mice were unable to sustain Th17 cell development in MLN in vivo, although CD103(+)CD11b(+) MLN DCs were able to do so in vitro.

Findings collectively point to a critical function for IRF4-dependent, IL-6-producing CD103(+)CD11b(+) DCs in intestinal Th17 cell development.

The transformation of a stem cell from one type to a differentiated one is known as cellular differentiation. Usually, the cell transforms into a more focused kind. Multiple instances of differentiation take place while a multicellular creature develops from a straightforward zygote to a complex system of tissues and cell types.

As adult stem cells divide and produce completely differentiated daughter cells during tissue repair and normal cell turnover, differentiation continues throughout maturity. In response to antigen exposure, some differentiation takes place. Size, shape, membrane potential, metabolic activity, and signal responsiveness of a cell all undergo significant changes during differentiation.
