Answer:
Colonization by plants may provide habitat, facilitating colonization of animal species.
Early colonizing plants may increase the nutrient level of the soil, facilitating the colonization of other plant species.
Animal colonizers may increase pollination of some plant species, facilitating their colonization.
Explanation:
The plants provides habitat as well as food to organisms that helps in the colonization of that organisms because every organism needs food and living place for its survival. Some plants increase the nutrient level in the soil through fixation of nitrogen which leads to the colonization of other plant species in that environment. Some animals causes pollination of plants which helps them in their colonization so all these organisms have a positive impact on the occurrence of other species.

Which elements are likely to have similar properties to calcium because they have the same number of valence electrons as calcium
Answer:
The correct answer would be - strontium, magnesium, beryllium.
Explanation:
As we know that the number of the same valence electrons is most likely to exhibit similar physical and chemical properties so the elements of the particular group in the periodic table have a similar number of physical and chemical properties and a similar number of the valence electrons.
For example, group 2 elements are known as alkaline earth metals, and strontium, magnesium, beryllium, and calcium are the same group elements thus, they have the same chemical and physical properties as they have 2 valence electrons.

Dominique is a chemist and has just discovered a new drug that interferes with the Calvin Cycle of photosynthesis. They believe this drug is going to be awesome because it will allow the light reactions to run forever, while just stalling out the Calvin cycle. Terry disagrees, saying that any drug that stalls Calvin will ultimately inhibit the light reactions, too. Who is correct and why
Answer:
Terry is right.
Explanation:
Any drug that stalls Calvin will ultimately inhibit the light reactions because the Calvin cycle and light reactions are interconnected. The light reactions provide CO2 to the Calvin cycle while on the other hand, the Calvin cycle provides sugars to light reaction in order to produce ATP molecules from it so if Calvin cycle stops no sugar is provided to the light reaction for generating ATP molecules.

Answer:
Hibernation helps animals survive the changing seasons. Foods that bears eat, such as berries and flowers, are much less available during cold winter months. When they hibernate, bears enter a deep sleep. ... While they sleep, the bears can survive because their bodies live off of their stored fat or food.
During hibernation, the animal’s body temperature, heart rate and breathing rate all drop to significantly lower levels. Animals do this to survive the winter because the weather is cold and food is scarce. It is advantageous because these animals can quite literally shut themselves off for weeks at a time rather than try and survive through harsh weather conditions.
While many people think bears are hibernators, they actually participate in a similar, though not exact, practice. Instead of hibernating, bears fall into a deep sleep called torpor. During torpor, heart rate and breathing rate decreases, body temperature reduces slightly and bears do not eat or release bodily waste. Bears can sleep more than 100 days without eating, drinking, or passing waste!
Bears sleep in dens that they make themselves, as well as in hollow trees, caves and dens built by other bears. A den can be built in 3–7 days, however, the timing of den building varies from bear to bear. While some bears build their dens months before hibernation season, others choose to excavate their dens.
These animals can dramatically drop their body temperature to below freezing—salty body fluids work to prevent tissue crystallization in particularly cold temperatures.
So really, animals that are true hibernators don’t actually sleep through the entire winter.
The urea produced by their fat metabolism is broken down and the nitrogen is re-used by the bear to rebuild protein.

Describe two types of tumors, and indicate which type is harmful and which is not.
A benign tumor is not a malignant tumor, which is cancer. It does not invade nearby tissue or spread to other parts of the body the way cancer can. In most cases, the outlook with benign tumors is very good. But benign tumors can be serious if they press on vital structures such as blood vessels or nerves. A malignant primary tumor is more dangerous because it can grow quickly. It may grow into or spread to other parts of the brain or to the spinal cord. Malignant tumors are also sometimes called brain cancer.

Plants, like all organisms, adapt to the conditions of their environment. Some special challenges a plant may face are drought, flooding, and a salty environment. Your task is to identify and describe ways that plants adapt to these challenging conditions in their environment. Select one plant adaptation to drought, one adaptation to flooding, and one for salt tolerance. Explain how each adaptation enhances plant survival. Identify a scholarly source of information for each
Answer:
Hydrophytes is flood tolerant plants, barley is salt tolerant crop and sorghum is a drought tolerant crop.
Explanation:
Hydrophytes also known as flood tolerant plants that have adaptations to survive flood problems. The plant has the development of air spaces in the roots and stems which allow diffusion of oxygen from the aerial portions of the plant into the roots. Barley shows a greater degree of salt tolerance by applying method of osmoregulation which helps the plant to tolerate salt stress. Sorghum is a plant that is adapted to drought condition. These plants have less number of stomata and waxy layers on the leaves which lowers the rate of evaporation or transpiration.

A. All of the fish eggs are genetically identical with one another and with the female parent fish.
B. The environment cannot support unlimited growth of the fish population, so only some fish eggs will mature to adults.
C. After the female fish lays a clutch of eggs, neither parent tends to or cares for the eggs or offspring.
D. Fish eggs will develop into embryos only if they are fertilized by sperm from the male fish.
Answer:
D
Explanation:
A can't be the answer since there is something called mutation which means even twins can't be 100% the same
B can't be since it has nothing to do with natural selection
C can't be sine as B, it has nothing to do with natural selection
A female fish may lay thousands of eggs at once. The additional statement about the fish which is most useful for explaining that the fish species can evolve by natural selection is that the fish eggs will develop into embryos only if they are fertilized by the sperm from the male fish. Thus, the correct option is D.
What is Natural selection?Natural selection can be defined as the differential survival and reproduction of the individual species due to the differences in phenotype of the organism. Natural selection is a key mechanism of evolution, the change in the heritable traits or characteristics of a population which take place over the period of several generations.
A female fish may lay thousands of eggs at once.

9. Which nucleus has role in conjugation in Paramecium
a) Mega nucleus
b) Micronucleus
c) Macronucleus
d) Cellular nucleus
( b ) Micronucleus has role in conjugation in paramecium.
The organism's germ line genetic material is kept in the micronucleus. It is in charge of the genetic rearrangement that takes place during conjugation and generates the macronucleus (cross-fertilization). Thus option B is correct.
What Micronucleus role in conjugation in Paramecium?The pairing and subsequent fusion of two paramecia is a process known as conjugation. It is known as a cytoplasmic bridge where they converge. After meiosis, the diploid micronucleus divides into four new micronuclei. The micronuclei of the cell, all except one, break down.
This method doesn't include meiosis or nuclear fusion. It manifests in a single person in the manner described below: Macronucleus deteriorates and vanishes. Eight nuclei are produced after the two micronuclei divide twice through mitosis.
Therefore, Micronucleus has a role in conjugation in Paramecium.

What is biomass burned to produce
Answer:
Burning either fossil fuels or biomass releases carbon dioxide (CO2), a greenhouse gas. However, the plants that are the source of biomass for energy capture almost the same amount of CO2 through photosynthesis while growing as is released when biomass is burned, which can make biomass a carbon-neutral energy source.
