Answer:
Wildfire help restore soil nutrients - Wildfire kills off the soil organisms that consume soil nutrients. Wildfires restore soil nutrients by decreasing the amount of underbrush in forests that contribute to nutrient loss. Wildfires break down organic material faster than decomposition, thus renewing soil nutrients more quickly.
Explanation:
Wildfire help restore soil nutrients by eliminating soil organisms that consume soil nutrients and decomposition of materials that help to renew soil nutrients.
What is soil nutrients?
Soil nutrients are essential ingredients needed by plants for growth, they include nitrogen (N), phosphorus (P) and potassium (K).
Some factor can impact on soil nutrients thereby reducing it.

ii. All existing cells are produced by other living cells.
iii. The cell is the most basic unit of life.
7. Cell theory is one of the great unifying theories of biology
Explanation:
Cell theory is one of the central theories of biology and is universally accepted. It states that all organisms are cellular - that is they are made of cells. It also states that all living things come from other living cells (not spontaneously, or from dead cells). The cell is the most basic unit of life, organisms can be unicellular, but no living thing is 'less' than that.
Explain how horned toads squirting blood from their eyes is a particularly good defense against coyotes.
Answer:
A stream of nasty-tasting blood squirts from the toads eyes, straight into the coyote's mouth. The coyote steps back, shaking its head from side to side in disgust. It retreats, wiping its muzzle, while the uninjured toad skitters away to safety.
Answer:
Horned toads squirting blood from their eyes is a good defense against coyotes because squirrels are much smaller than coyotes so they can't fight back. The blood scares the coyotes and makes them run away so that the squirrel can survive.

The movement of glucose across the membrane through facilitated diffusion is a form of passive transport because
Answer:
Explanation:
Glucose is a 6 carbon sugar molecule that provides energy needed by cells. Since glucose is a large molecule, it is difficult to be transported across the membrane through simple diffusion. Therefore, it diffuses across membranes through facilitated diffusion down the concentration gradient.
Indicate which the following statements are true.
a. During glycolysis, glucose molecules are hydrolysed to yield CO2 and H2O
b. The cleavage of fructose 1,6-bisphosphate by phosphofructokinase yields two molecules of glyceraldehyde 3-phosphate.
c. When subjected to anaerobic conditions, glycolysis in mammalian cells continues and causes a buildup of pyruvate in the cytosol.
d. In the mitochondrial matrix, the pyruvate dehydrogenase complex produces CO2, acetyl-CoA and NADH.
e. Fatty acids can be transported into mitochondria and converted into acetyl-CoA, FADH2 and NADH
Answer:
The correct answer is: D
Explanation:
(a) This process does not occur during glycolysis, it occurs after glycolysis since pyruvate is generally accepted to be the last product of glycolysis
(b) Phosphofructokinase does not produce two molecules of glyceraldehyde 3-phosphate but rather produces of one molecule of glyceraldehyde 3-phosphate and dihydroxyacetone phosphate
(c) During anaerobic conditions in mammals, pyruvate is converted to lactate by the enzyme lactate dehydrogenase. It can actually cause the accumulation of lactic acid/lactate in the muscle which causes muscle fatigue but does not cause buildup of pyruvate in the cytosol.
(d) In the fate of pyruvate, the pyruvate dehydrogenase complex produces CO2, acetyl-CoA and NADH in the mitochondrial matrix. The acetyl-coA produced thereof serves as a precursor for the citric acid cycle.
What do some scientists today believe causes more adaptations' competition or environmental changes?
Answer:
According to an April study, table corals (Acropora hyacinthus) can adapt to resist bleaching in warmer waters. On Ofu Island in American Samoa, A. hyacinthus lives in both hot and cool pools. In the lab, researchers tested corals from both environments to see how they reacted to increased heat.
Explanation:

Some scientists today believe that adaptations are more caused or provoked by the fact of competition.
What is meant by Adaptation?Adaptation may be defined as the process that significantly involves the modification of internal and external attributes of organisms that makes them fit for survival and reproduction in the natural environment.
Competition is because of the fact that as the diversity of organisms increases, the resource limits remarkably enable the organisms to activate the mechanism of competition. Due to this, each and every species makes itself superior in order to make their survival in the natural environment.
Therefore, some scientists today believe that adaptations are more caused or provoked by the fact of competition.

Cane toads are large, nonnative, poisonous toads in Australia. After cane
toads entered Australia, scientists observed that the average head size in a
population of toad-eating snakes was getting smaller. Snakes with smaller
heads are not able to eat the large cane toads. What type of situation is this?
O A. Disruptive selection
B. Species richness
C. Directional selection
D. Genetic variation
The answer you are looking for is C
Natural selection is a process by which the organisms adjust to the variation in the environmental conditions so they can endure and thrive in the altered conditions.
The correct answer is:
Option C. Directional selection
This can be explained as:
Directional selection is a negative form of natural selection in which the inhabitants of one species is favoured over another.The species with better trait characteristics will be favoured over the organism with less preferred attributes.The allele recurrence in directional assortment shifts over time.Therefore, toads with better traits (head size) are favoured over snakes with smaller mouth sizes.

Explanation:
With increasing maternal age, the chances of observing trisomies increase significantly. Increasing paternal age is associated with de novo point mutations. Why?
Answer:
Mother: higher risk of an improper chromosome division
Father: higher risk to suffer point mutations in sperm cells
Explanation:
A trisomy is an alteration in the chromosome number (i.e., an aneuploidy), and occurs when a cell receives three chromosomes instead of two. The risk of aneuploidies -including trisomies- increases with the mother's age due to the fact that older eggs have a higher chance of dividing unequally, thereby leading to an imbalanced number of chromosomes between daughter cells. Moreover, a point mutation is defined as a genetic modification where a single nucleotide is changed in the DNA sequence. It has been shown that point mutations in children are determined to a large extent by the father’s age, which are due to mutations in germline cells (i.e., sperm cells) that were passed to the progeny. A child born from a father who is 20 years old exhibits on average 40 point mutations, whereas a child born from a father who is 40 years old has typically twice the point mutations on its genome.
Which statement best describes the difference between the crust and the lithosphere?
A. The lithosphere contains both the crust and the upper most rigid layer of the mantle
B. The lithosphere contains both the crust and the inner core
C. The lithosphere contains both the core and the mantle
D. The lithosphere contains both the crust and the ocean
Answer:
A. The lithosphere contains both the crust and the uppermost rigid layer of the mantle
Explanation:
The statement that describes the difference between the crust and lithosphere is that the lithosphere contains both the crust and the uppermost rigid layer of the mantle.
The earth is divided primarily into 3 concentric layers; crust, core, and mantle. The crust is the outermost layer of the earth. It is a very thin layer. The lithosphere, on the other hand, is the crust plus the upper rigid layer of the mantle. This is the main difference between the crust and lithosphere.Which of the following things is common to all living organisms?
