list five evidence of photosynthesis and describe any two
Answer:
Hi there, I will help you
Explanation:
It houses glucose, which plants use for food. The presence of starch in a leaf is reliable evidence of photosynthesis. That's because starch formation requires photosynthesis.
Which defensive adaptation would best help a plant survive in an environment with leaf-eating animals?
A.
large fruits
B.
thick stems
C.
sharp thorns
D. colorful flowers
Answer:
C. sharp thorns
Explanation:
The plants stand still, are not very physically active, and seem to be on the menu of many animals. Precisely because they cannot win at the first sign of danger, one has developed other ways in which they can defend themselves from annoying and dangerous animals.
Some have developed long thorns that repel attackers. Some have poisons that are very strong and because of which animals do not think of trying to eat that plant, but the defense of some plants seems to be well thought out and ready for all forms of attack.
Plant cells are surrounded by a cell wall. What is the function of this structure?
Answer:
The function of a cell wall is to protect and support the organism.
Explanation:
Why do cells divide rather than get bigger?
1)the can't get bigger
2)the bigger they get, the less efficient they are and can't 3)not meet the needs of the cell
4)diffusion is enough for the cells to grow

A population of Muscovy ducks contains 13 birds with black masks and 37 birds with red masks. Red masks are the dominant trait. What is the frequency of the black allele? What is the frequency of the red allele? What is the frequency of heterozygotes?
Answer: Black allele has frequency of 0.14.
Red allele has frequency of 0.86.
The frequency of heterozygotes is 0.241
Explanation: Hardy-Weinberg model states the frequency of alleles in a population will stay in equilibrium as long as there are external influences. It is also used to determine alleles frequencies using the following equations:
[tex]p+q=1[/tex]
[tex]p^{2}+2pq+q^{2}=1[/tex]
p represents frequency of dominant allele;
q represents frequency of recessive allele;
2pq is frequency of heterozygotes;
For the frequency of red allele, which is dominant, we can use:
[tex]p^{2}=\frac{37}{13+37}[/tex]
[tex]p^{2}=\frac{37}{50}[/tex]
[tex]p^{2}=0.74[/tex]
[tex]p=\sqrt{0.74}[/tex]
p = 0.86
For the black allele:
[tex]p+q=1[/tex]
[tex]q=1-p[/tex]
[tex]q=1-0.86[/tex]
q = 0.14
Frequency of heterozygotes is
2pq = 2(0.86)(0.14)
2pq = 0.241
Frequencies for a population of Muscovy ducks are 0.86 for red allele, 0.14 for black allele and 0.241 for heterozygote.

Warm ocean currents originate near the equator and move towards the poles or higher latitudes while cold currents originate near the poles or higher latitudes and move towards the tropics or lower latitudes. The current's direction and speed depend on the shoreline and the ocean floor.
how does geographic isolation cause an increase in differences between two groups
Answer:
What was once a continuous population is divided into two or more smaller populations. This can occur when rivers change course, mountains rise, continents drift, or organisms migrate. The geographic barrier isn't necessarily a physical barrier that separates two or more groups of organisms. It might just be unfavorable habitat between the two populations that keeps them from mating with one another.

1. Consider the statement: "Sickle cell disease is a(n)
disease."
Which of the following terms could fill in the blank to make the statement true? Write "yes" or "no" next to each
possible response. There may be more than one correct answer.
Genetic
Infectious
Potentially lethal
Inherited
Answer:
Genetic = yes
Infectious = no
Potentially lethal = yes
Inherited = yes
Explanation:
"Sickle Cell Disease" is a blood disorder that is mostly inherited. An example of this is the "Sickle Cell Anemia," which means the body of the person is lacking in red blood cells. In order for an infant to carry such disease, both of his parents must pass the defective gene to him. It is a potentially lethal or deadly disease because if not given remedy, it may lead to several complications such as organ damage, leg ulcers, blindness, etc.
It is not infectious, which means that a person with a Sickle Cell Disease cannot transfer it to another person. It is not likely to spread as well.

Explanation:
2. What are genes, and how are they related to alleles and chromosomes? Start with the definitions of genes and alleles. (2 points)
Answer:
Genes are portions of DNA that contains information to encode proteins
Alleles are different forms of one gene
Chromosomes are closed circular DNA molecules that contain the genetic material of an organism
Explanation:
Genes can be defined as regions of DNA which are transcribed to produce messenger RNAs (mRNAs) by a process known as transcription. Subsequently, these mRNAs are translated into proteins. In diploid organisms, each gene contains two different forms called alleles. A chromosome is a long DNA molecule that contains part or even the entire genetic material of an organism. In diploid organisms, one chromosome contains one allele (inherited from one parent), while its homologous chromosome pair contains another allele of the same gene (inherited from the other parent).
What characteristic of water causes water to stick to the side of a test tube?
I need a claim, evidence, and reasoning !
Answer:
The characteristic of water that makes this liquid stick to the side of a test tube is called capillarity (Claim).
Explanation:
Water (H₂O) is a polar molecule with the ability to generate van der Waals forces, which is explained by the 4 hydrogen bonds it forms to bind to other substances. The consequence of the forces of the molecular bonds are four properties of H₂O, including surface tension, cohesion, adhesion and capillarity.
- Claim: The characteristic of water that makes this liquid stick to the side of a test tube is called capillarity.
- Evidence: Cohesion and adhesion of water are properties that come from the forces of the molecular bonds of water, and whose effect is the ability of water to wet surfaces and adhere to a tube that contains it, the latter due to capillarity. Capillarity also allows water to rise through the roots and stems of plants, through their thin vascular ducts.
- Reasoning: cohesion in water depends on the force of attraction between H₂O molecules, adhesion is the capacity of H₂O molecules to join other different molecules and —together with surface tension— make H₂O molecules close to the walls of a glass tube adhere to it, which represents capillarity.
The effect of capillarity is more evident when the test tube is of a smaller diameter, although capillarity and adhesion to its walls always exist, and to a greater degree than any other substance.
will mark as brainleist
Answer:
B is correct
Explanation:
A is incorrect because the type of carbon that comes from food is not carbon dioxide.
C is incorrect because the carbon dioxide that comes from factories is part of that cycle, which mean there is no extra carbon, it's just an extra carbon molecule.
D is incorrect because as everyone knows, factories are not living things.

During a lion and cub moment, Mufasa says to Simba, “Everything you see exists together in a delicate balance…..respect all creatures”. How can this quote be related to the concept of the food web, pyramid of energy, and/or the pyramid of numbers? What could happen if this balance is not respected? Indicate a scene in the movie that is an example of this loss of balance.
Answer:
The quote refrences to the fragility of our enviorment and how that balance is to not be disrupted. That no matter how small,every detail affects that balance and is not to be tampered with. It is the same in the food chain,the elimination of even the smallest of species can have devastating effects on an ecosystem. That is why it is important to preserve resources and respect all life. an example of that balance being disrespected in the movie would be the scene where the once beautiful valley was barren and dry due to the hyenas destroying and using up all of the resources, thus destroying the balance of life and bringing famine to their lands.
Explanation: The circle of life man
When a balance is not respected then it leads to destruction of the whole ecosystem not a single organism.
What is the relation of the quote?This quote is related to the concept of the food web, pyramid of energy, and the pyramid of numbers because every organism is dependent on other organism for its survival. If that organism is eliminated from the ecosystem, then the organism that feeds on it also die.
If this balance is not respected and maintained then the whole ecosystem is destroyed because every organism is dependent on othe organism.
So we can conclude that when a balance is not respected then it leads to destruction of the whole ecosystem not a single organism.

the number of two digit is equal to four times the sum of digits. if the product of digits is 8 .find the number.
Answer:
I think you are only intended to find
24
Explanation:
10x + y = 4(x + y) Remove the brackets
10x + y = 4x + 4y Subtract 4x from both sides
10x - 4x + y = 4x - 4x + 4y Combine like terms
6x + y = 4y Subtract y from both sides
6x + y - y = 4y - y Combine
6x = 3y Divide by 3
6x/3 = 3y/3
2x = y
Put this result in the equation below
x*y = 8
x(2x) = 8
2x^2 = 8 Divide by 2
2x^2/2 = 8/2
x^2 = 4 Take the square root.
√x^2 = √4
x = ± 2
y = 2*x = ±4
Answer
The plus answer for x and y is the one we'll see about first.
10x + y = 20 + 4 = 24
24 =? 4(2 + 4)
24 =? 4*6 = 24
The product of it's digits = 2 * 4 = 8.
24 is definitely one answer.
========================
What about -2 and - 4
-24 = 4(-2 + -4)
-24 = 4*-6 = -24
