Answer:
Hello your question is incomplete attached below is the complete question
answer :
None of the progenator cells differentiate into type 2 cells. ( A )
Explanation:
Due to the loss-of- function mutation in the gene for the Notch receptor in the progenitor cell of C elegans , This causes The progenator cells for type 1 to be differentiated to type 1 cells but the cells for type 2 will not be differentiated.
hence the answer is : None of the progenator cells differentiate into type 2 cells.

Commensalism is a symbiotic relationship in which one organism benefits and the other organism neither benefits nor is harmed.
Mutualism is a symbiotic relationship in which both organisms benefit.
Parasitism is a symbiotic relationship in which one organism benefits and the other organism is harmed.
Predation is a relationship in which one organism preys on (and eats) another organism.
Competition is relationship in which two organisms must fight (directly or indirectly) for resource
Objective:
Given a description of the relationship between two organisms, determine if their relationship is competition, commensalism, predation, mutualism, or parasitism.

The fungus helps the plant absorb inorganic nitrogen and phosphorus from the soil. Some fungi also secrete antibiotics, which can help protect the plant from parasitic fungi and bacteria. _______________________________

As soil particle size decreases, capillary action will
Answer:
Increases
Explanation:
The smaller is the size of the soil, the greater is the interspace distance between the two soil particles. As this distance increases, the water gets more space to travel through thereby increasing the capillary action. Hence, as the size of soil particle reduces, capillarity increases.

⭐Is there an advantage for the different anole species being able to occupy different parts of a habitat?
Yes, since the Anolis sagrei inhabits humid lowland forests and dry lowland forests. Apparently it prefers areas that have very low or little ground cover (18, 23).The green anole lizard, Anolis carolinensis, has adapted to living in the tree canopy and can lead to speciation, Different species of anoles have different dewlaps, and very different vegetation.

The diagram below shows a diploid cell with two homologous pairs of chromosomes. Due to independent assortment and crossing-over, the possible allelic combinations that could be found in gametes by the meiotic division of this cell are _________________.
A
Bb, Dd, BB and DD
B
BD, bD, Bd and bd
C
BBDd and BDbd
D
Bd and bD only
Due to independent assortment and crossing-over, the possible allelic combinations found in gametes by the meiotic division of this cell are B and D can be on one chromosome, while b and d can be on the other. Therefore, the correct answer is (B) BD, bD, Bd, and bd.
What is crossing-over?Crossing-over is a process that occurs during meiosis, the cell division process that produces gametes (sperm and egg cells) in sexually reproducing organisms. During crossing-over, homologous chromosomes exchange genetic material, resulting in the creation of new combinations of alleles.
What is the law of independent assortment?The law of independent assortment is a fundamental principle in genetics that describes how different genes are inherited independently. Gregor Mendel first proposed this principle.

Vacuoles are found in plats, animals, and single-celled organisms.
In plants, vacuoles can occupy up to 90% of the cell while in animals, vacuoles are much

Single-celled organisms that live in aquatic environments like the paramecium, have a
contractive vacuole to maintain homeostasis.
Based on the information given, how does a vacuole help an organism maintain homeostasis?
A. It helps by regulating water amounts within the cell.
B. It helps by keeping a rigid structure at all times,
C. It helps by excreting salt as part of osmosis
D. It helps by controlling the movement of gases into the cell.

3) identify and describe three abiotic characteristics of ecosystems. Give an example of how each
characteristic could be affected by a human activity
Answer:
The abiotic characteristics of an ecosystem that affects man includes: Land surface, rainfall and relative humidity.
Explanation:
In the ecosystem, man occupies the terrestrial habitat which is affected by the abiotic factors listed above.
Abiotic (non- living) factors determine the type of biotic (living) community that is found in an ecosystem. These factors include Land surface, rainfall and relative humidity, just to mention a few.
--> LAND SURFACE: This is responsible for the marked variation in the vegetation of a place. For example, a mountain in the tropics may have a rain forest vegetation at it's base and an afroalpine vegetation near its peak. The gradient of the slope affects the growth of organisms. A steep slope encourage fast run - off of water and therefore encourages erosion, which results in shallow and infertile soil. This in turn AFFECT man's farming activities as there would be little to no crop yield.
--> RAINFALL: Water is a very important abiotic factor that affects life. The main source of water to terrestrial habitat is rainfall. When rain falls, a greater percentage of it sinks into the soil while the rest run- off into water bodies. Water is absorbed by root hairs into the plant and used for photosynthesis to produce food. The absence of rainfall in the environment of man could lead to drought which AFFECTS man negatively.
--> RELATIVE HUMIDITY: This is a measure of the amount of moisture in the atmosphere. It's usually high in hot wet regions. It affects the rate at which water evaporates from the body surfaces of organisms. Low relative humidity cause more water (sweat) to evaporate from body surfaces giving the human body a cooling effect. But in high relative humidity, the sweat cannot evaporate leaving the body feeling hot and sticky. This AFFECTS man as the body tries to cool off in a harder way by increasing rate of respiration and depth of blood circulation.
The diagram shows the same type of molecules in area A and area B.
With the passage of time, some molecules move from area A to area B. This movement is the result ot the process of
1. phagocytosis
2. pinocytosis
3. diffusion
4. cyclosis
Answer:
3. diffusion, because molecules are moving from a high concentration(A) to a low concentration(B)
Diffusion is the net flow of matter from a location of high concentration to a region of low concentration as a result of the random mobility of molecules. Both stopping and reversing this process are not possible. Thus, option C is correct.
What are the main mechanism in diffusion process?The molecules' kinetic energy causes random motion, which causes diffusion. This mechanism happens in simple diffusion without the help of a carrier protein.
The molecules travel from an area of high concentration to an area of low concentration due to their random mobility.
Chemicals flow across the plasma membrane from areas of high concentration to areas of low concentration in cells to maintain an equilibrium (balance) of internal substances.
This implies that if there are more items inside the cell than outside, they will go outside and vice versa. It happens when the medium around the cell contains more water than the cell itself.
Therefore, This movement is the result of the process of diffusion.

Answer:
They move
Explanation:
Answer:
A tectonic plate (also called lithospheric plate) is a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere.Plate tectonics move because they are carried along by convection currents in the upper mantle of the planet (the mantle is a slowly flowing layer of rock just below Earth's crust). Hot rock just below the surface rises and when it cools and gets heavy, it sinks again.
