What is NOT an adaptation that pioneer species need? *
A. ability to do photosynthesis
B. live without soil
C. the ability to grow tall
D. tiny roots to break down rock
Explanation:
Primary succession, type of ecological succession (the evolution of a biological community’s ecological structure) in which plants and animals first colonize a barren, lifeless habitat. Species that arrive first in the newly created environment are called pioneer species, and through their interactions they build a simple initial biological community. This community becomes more complex as new species arrive. Primary succession is distinguished from secondary succession, which is the recovery of an existing biological community after a disturbance sets back the community’s ecological structure to an earlier stage.
5 5. Normally, the temperature inside the scrotum is slightly lower than normal body temperature. What do you predict would happen if the temperature inside the scrotum were a few degrees higher than normal body temperature instead? A. Sperm would not be able to travel through the vas deferens. B. Sperm would be stored in the epididymis rather than in the testes. c. Sperm would not be able to develop properly. D. The rate of sperm production would increase,
Answer:
C. Sperm would not be able to develop properly.
Explanation:
There is an optimum temperature where sperm production is at its best. An increase or decrease in temperature may affect the quality and quantity of the sperm.
If the temperature inside the "sc-rotum" raises by few degree than normal body temperature, than the "sp-erm" would not be able to develop properly.
What is the function of "sc-rotum"?A pouch, which is suspended from the groin, and comprising the "tes-tes" and some of the male "s-ex" accessory ducts is known as the "sc-rotum". The prime function of the "sc-rotum" is to maintain the temperature essential for the process of "sper-matogenesis", that is, by situating the testes external of the body cavity.
Within the human "sc-rotum", the temperature is 3.1 degree C lesser than the usual temperature of the body. In case, if the temperature elevates of the "sc-rotum", the degeneration of the germinal epithelium will take place, which will eventually result in sterility. Therefore, for the production of sperms within the testes, a lower temperature is needed, otherwise the development of the "sp-erm" will not take place appropriately.
Thus, the correct answer is option C.

In the formation of pollen grains, the nucleus in the pollen will divide by mitosis to form two nuclei. Justify.
Answer:
The other two, the generative nuclei, can be thought of as non motile sperm cells. After reaching an ovule and breaking out of the pollen tube tip, one generative nucleus unites with the egg cell to form a diploid zygote.
Explanation:
This means that;
The fertilized egg with two complete sets of chromosomes, one from each parent. The zygote undergoes a limited number of divisions and gives rise to an embryo.

15. Cells found in plants and animals have similarities but can differ in function. Consider the following two organisms: a corn plant cell (Zea mays) and a camel cell (Bactrianus ferus). What is the best explanation for the difference in the cellular vacuole size between these two biotic organisms?
A. The corn cells' have a small vacuole size because it does not need long term water and
electrolyte storage.
B. The camel cells' have a small vacuole size because it does not need long term water and electrolyte storage.
C. The camel cells' have a small vacuole size because it is not in contact with toxins that need to be removed from the cell.
D. The corn cells' have a large vacuole size because it is in contact with many toxins in the soil which need to be removed from the cell.
The best explanation for the difference in the cellular vacuole size is option d. The corn cells' have a large vacuole size.
Explanation to the difference in the cellular vacuole size:When there is the difference in the vacuole size that lies between the two biotic organism so it is due to the corn cells that contain high vacuole since they are in contact with various toxins in the soil that need to be eliminated from the cell.
hence, the correct option is d.
And, the rest of the options are wrong.

Tongue rolling is a dominant trait. Explain why it is possible for both parents being able to roll their tongue but their biological child is not able to do so.
Answer:
The answer is 0 ( AKA A )
Explanation:
Parents form the same type of gene, which is Rr. Since all the genes are the same, there can not be a chance that the offspring can not roll the tongue. Next time focus on your work!! :3

A one-hectare forest community is sampled in early August. The sample yields 12 small trees, 4 types of vines, as well as 17 native shrubs that represent 10 species. What can be estimated from the sample for the shrubs in the forest community?
A. the forest’s productivity
B. the species richness
C. the degree of forest disturbance
D. the stability of the ecosystem
E. the uniformity of species distribution in the ecosystem
Answer:
The correct answer is - B. the species richness
Explanation:
Species richness determines the numbers of different species are present in an ecological community. It is a numerical value or count of different species present in a particular community.
The given information or data can only be used to estimate the species richness in the particular forest community as there is data available about the number of species presnt in this community.

What are Tectonic Plates made of and what do they do?
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.

explain how carbon atoms can move to co2 in the air into an organic molecule inside a plant and then back to co2 in the air
Answer:
Your carbon atom enters the leaf as CO2 (carbon dioxide) from the atmosphere. In the leaf, chlorophyll uses the energy from the sun to convert CO2 and H2O to the sugar glucose, C6H12O6. Your carbon atom is part of this molecule; it is now one of the carbons in the glucose.
Next, the glucose carrying your carbon atom is sent down the phloem tissue of the carrot plant to the root, which is the carrot itself. Enzymes in the carrot root connect the glucose molecule with your carbon atom into a chain with other glucose molecules, forming cellulose, or plant starch, and there you go. Your carbon atom went from being part of an atmospheric gas to a starch via photosynthesis and starch formation in the root.

Why might parents who don't show the trait of albinism have children who do?
Answer:
This trait is rare when it occurs. Some genes depend on other genes to be expressed, so in most cases a trait is denied an expression. But its still there, so it passes down to generation until it gets expressed.
Explanation:
Answer:
Because it's a recessive trait
Explanation:
There are two chromosomes that determine your biological sex: XX for the female and XY for the male. You inherit one X chromosome from your mother and one X or Y chromosome from your father, which is what determines your sex.
A certain inheritable genetic condition can be recessive or dominant. If it's dominant, it shows even if just one chromosome carries that condition. If it's recessive, it has to be in both ones (or just the x one or just y if you're male. That's why some conditions, such as daltonism, affect men more that women).
For example, blue eyes are a recessive trait, brown eyes are a dominant trait. If your parents are both blue eyed, you will surely have blue eyes as well. The same can't be said if both of your parents have brown eyes: they might still be carrier of the blue eyed trait (both of them have to), in which case you would have a 25% chance (1/4) to have blue eyes (½ to inherit the carrier chromosome from your mother; ½ from your father). The same can be said about albinism
predict if a coelomate or an acoelmate would be larger
Answer:
Explanation:
A coelom is a hollow space surrounded by tissues. The basic structure of most animals comprises three tissue layers, an interior endoderm and an exterior ectoderm that are separated by a mesoderm. Typically, the endoderm forms the innermost digestive tract, the ectoderm the outermost skin layer, and the remaining internal organs are formed from the mesoderm. In derived animals, the endodermal tube is suspended from the dorsal and ventral surfaces by mesoderm, so as to leave open coeloms that allow circulation of fluids. Advanced circulatory systems develop from these coeloms.
