Four substances are important for both photosynthesis and cellular respiration: oxygen, glucose, carbon dioxide, and water. What is the best explanation for how for both processes use these substances?
1.) both produce atp at some point
2.) both make glucose at some point
3.) both require oxygen gas at some point
4.)both include the keens cycle at some point
Answer:
The answer is 4, I got this correct on a Plato test on edmentum
Explanation:
Photosynthesis and cellular respiration are the metabolic processes, in which organisms gain energy from the metabolization of oxygen, glucose, carbon dioxide, and water.
The correct answer is:
Option A. both produce ATP at some point
Photosynthesis is the process of producing glucose and evolving oxygen, whereas cellular respiration is the process of breaking glucose to yield energy, such as:
In photosynthesis, the light-independent reactions or Calvin cycle involves the generation of ATP and NADPH. In cellular respiration, Kreb's cycle is involved in the generation of ATP and NADH, which then enter the electron transport chain.Thus, the process has similar raw materials that are metabolized to generate ATP at some point.
Therefore, option A is correct.

Describe what happens as a plant's turgor pressure increases and decrease AS MUCH POINTS AS I CAN GIVE
Answer:
Brainliest pls
Explanation:
Turgor pressure in plants. Turgor pressure within cells is regulated by osmosis and this also causes the cell wall to expand during growth. Along with size, rigidity of the cell is also caused by turgor pressure; a lower pressure results in a wilted cell or plant structure (i.e. leaf, stalk).
Turgor pressure in plants plays a key role in processes such as growth, development, mechanical support, signalling, flowering and stress response. Turgor pressure is an ideal means in plant cells through which the energy content of water molecules (water potential) can be adjusted quickly, within seconds.
Viruses, such as influenza, are often spread through droplets made when infected people cough, sneeze, or talk. After a virus infects a new host, it begins to reproduce. Which statement about viral reproduction is

Decide whether the scale factor will produce an enlargement or a reduction. Scale Factor = 5/2. Enlargement Enlargement Reduction
Answer:
Enlargement
Explanation:
Dilation is the enlargement or the reduction in the size of an object.
Enlargement is increase in size of an object. A figure is said to be enlarge if it is larger than the original figure.
Reduction is the decrease in size of an object. A figure is said to be reduced if it is smaller than the original figure.
The scale factor determines if it is either an enlargement or a reduction. If the scale factor is less than one then it is a reduction whereas if the scale factor is greater than 1 it is an enlargement.
Since it is a scale factor of 5/2, it is an enlargement.

If one parent has type B blood and the other type O blood what percentage of the child's blood will be B, O, A?
Answer:
If one parent has blood type B and the other parent has blood type O, the percentage of the blood type of the offspring will depend on the genotype of the parent with blood type B.
Explanation:
Knowing the blood type of the offspring of the cross between parents with blood type B and O raises two possible scenarios, depending on whether the genotype of the parent (type B) is B|B or B|O.
Blood type is an inherited trait and is characterized by the presence or absence of surface antigens A and B in the red blood cells, which genetically behave as co-dominant traits.
Blood type A contains antigen A and its genotype can be A|A or A|O. Blood type B contains the B antigen, whose genotype can be B|B or B|O. Blood type AB contains both antigens and a single A|B genotypic expression. Type O blood lacks surface antigens, and is the recessive trait so its genotype is O|O.Scenario 1: Parent with genotype B|B.
In this case, knowing that the genotype for type O is always O|O, all offspring would be of blood type B, genotype B|O.
B|B X O|O
Alleles B B
O B|O B|O
O B|O B|O
100% of the offspring would be of blood type B.
Scenario 2: Parent with genotype B|O.
In this case, 50% of the offspring will have blood type O and 50% B.
B|O X O|O
Alleles B O
O B|O O|O
O B|O O|O
In no scenario would offspring of blood type A be possible.

Which part of your integumentary system is found on the outside of your body? *
a. Epidermis
b. Keratin
c. Dermis
d. Melanin
Answer:
The correct answer is a. Epidermis.
Explanation:
The skin is made up of two layers that have different structure and origin: epidermis and dermis, which are closely related. The epidermis is the most superficial part of the skin and is made up of a keratinized flat stratified epithelial tissue, where several layers or strata can be seen that, depending on their greater or lesser development, allow the skin to be classified into thick and thin. The thick skin is on the palms of the hands and the soles of the feet and is characterized by a thick layer of keratin and by having a so-called lucid layer that does not exist in thin skin. Thin skin also has keratin, but the thickness of the keratin layer is much less. The epidermis is separated from the dermis by a limiting membrane, the basement membrane, which measures 50-70mm thick and is attached to the dermis by reticular fibrils that show axial periodicity.

A always pairs with T, so 56 A's will pair with 56 T's
G always pairs with C, so 44 G's will pair with 44 C's
100 base pairs means there are 200 bases present altogether
out of 200, we have 65 T's so ultimately we will have 65 A's
we are now left with 70, of which have will be C and half G, which gives 35 C's and G's

Explanation:
Sarah and Thomas are thinking about having kids. They are concerned that because Thomas’s father was diagnosed with cystic fibrosis last year, it could run in the family. Cystic fibrosis is a recessive genetic disorder which affects the respiratory system. Both Thomas and Sarah get tested for the recessive allele (f), with the results indicating that they are each carriers of the disorder (a genotype of Ff).
Is it possible for Sarah and Thomas to develop cystic fibrosis?
It is not possible for Sarah and Thomas to develop cystic fibrosis but it would be possible for one of their children to inherit it. Both Sarah and Thomas are heterozygous and in a heterozygous pair of alleles the dominant allele is the one that will present. Because Sarah and Thomas both have the heterozygous allele combination Ff they are carriers which means that they will not experience symptoms of cystic fibrosis but they could pass cystic fibrosis onto one of their children.
Why did the recessive trait for shortness come back in the second generation of Mendel's cross of tall and short plants?
Answer:
Mendel called the visible form the dominant trait and the hidden form the recessive trait. In the second generation, after plants were allowed to self-fertilize (pollinate themselves), the hidden form of the trait reappeared in a minority of the plants.

You run one lap around the track at a constant 11 km/h. What changes?
Answer:
Your velocity
Explanation:
This is because the direction is changing. The speed doesn't change since it's constant
When we run one lap around the track at a constant 11km/ hr., the velocity will change as we are changing the direction, speed will remain constant.
What is Velocity?Velocity is defined as the directional speed of a moving object that indicates the rate of change of position as observed from a particular frame of reference and as measured by a particular standard of time.
Velocity is the vector quantity as it has both magnitude as well as direction. Speed is the rate of change of distance while the velocity is the rate of change of displacement. It can be measured by the formula which is :
[tex]\overline{v}={\frac{\Delta x}{\Delta t}}\\\overline{v} = average velocity\\{\Delta x} = displacement\\{\Delta t} = change in time[/tex]
It's SI unit is m/s.
In the given information, the track is in circular form due to which the direction is changing resulting in change in velocity as it is the rate of change of displacement.
Thus, when we run one lap around the track at a constant 11km/ hr., the velocity will change as we are changing the direction, speed will remain constant.
