Answer:
Lysosomes
Explanation:
Lysosomes are membrane-enclosed organelles that contain an array of enzymes capable of breaking down all types of biological polymers—proteins, nucleic acids, carbohydrates, and lipids. Lysosomes function as the digestive system of the cell, serving both to degrade material taken up from outside the cell and to digest obsolete components of the cell itself. In their simplest form, lysosomes are visualized as dense spherical vacuoles, but they can display considerable variation in size and shape as a result of differences in the materials that have been taken up for digestion. Lysosomes thus represent morphologically diverse organelles defined by the common function of degrading intracellular material.
What structures in the human body carry out some of the same function as xylem and pholoem
Answer:
Veins arteries and capillaries
The structures in the human body that carry out some of the same function as xylem and phloem are veins, arteries, and capillaries.
What do you mean by Xylem and Phloem?Xylem and phloem are the vascular tissues that transport water, minerals, and food from the roots to the leaves and from the leaves to the roots respectively.
Xylem and phloem represent homology with the veins and arteries. Veins carry blood back towards your heart, while arteries carry blood away from your heart.
Capillaries are blood vessels that carry the oxygen and nutrients from the blood and transport them into the tissues and organs. It also requires the elimination of the waste products away from your tissues.

A sample of DNA contains 120 nucleotides, if 35 nucleotides are Guanine, how many nucleotides are Thymine?
(If you can show how you do it that would be great)
Answer:
25
Explanation:
In DNA, Guanine pairs with Cytosine, and Thymine pairs with Adenine. This tells us that there are equal numbers for each Guanine and Cytosine, and Thymine and Adenine. When there's 35 Guanine, there should be 35 Cytosine that goes with it. 120 - 2(35) = 50. The remaining 50 nucleotides are Thymine and Adenine, and since they are the same number, divide 50 by 2. 50 ÷ 2 = 25. There are 25 thymine in the sample of DNA.

WHICH LAYER OF THE SUN HAS THE DENSEST MATERIAL?
Answer:
The sun is a star, this means the sun generates energy from a process called nuclear fusion. During nuclear fusion, the high pressure and temperature in the sun's core cause nuclei to separate from their electrons. Hydrogen nuclei fuse to form one helium atom. During the fusion process, radiant energy is released.

How did gravity affect the growth of the germinating corn seeds?
Answer:
see below
Explanation:
their roots respond positively, growing down, into the soil, and their stems respond negatively, growing upward, to reach the sunlight.
Gravity influenced the growth of germinating corn seeds by providing the directional cue for root growth and promoting proper orientation of the plant.
Gravity plays a crucial role in plant growth and development, particularly during the germination of seeds. When a germinating corn seed is placed in a gravitational field, gravity acts as a guidance mechanism for the growing seedling.
In response to gravity, the root of the germinating seed grows in a downward direction, a process known as gravitropism or geotropism. This downward growth of the root is called positive gravitropism. The root responds to the gravity stimulus by redistributing auxin, a plant hormone, towards the lower side of the root. This causes cells on the lower side of the root to elongate more than cells on the upper side, leading to downward growth. The downward growth of the root helps anchor the plant in the soil and facilitates water and nutrient absorption from the ground.
Simultaneously, gravity also influences the shoot of the germinating corn seed. The shoot exhibits negative gravitropism, where it grows upward against the force of gravity. This upward growth is counterbalanced by the downward growth of the root, allowing the plant to establish proper orientation.
Without the presence of gravity, the germinating corn seeds would not be able to establish the proper orientation and direction of growth. The root may not grow downward, leading to irregular and inefficient water and nutrient absorption. The shoot may not grow upward, resulting in an abnormal and compromised overall plant structure.
Therefore, gravity serves as a crucial external factor that guides the growth of germinating corn seeds, ensuring proper root development, anchorage, and shoot orientation for successful plant growth.

How does natural selection enable species to changes their body shape, appearance, and/or size over time? *
A) Individuals that are better adapted to their environment survive and reproduce.
B) Overproduction provides food for stronger members of the species.
C) Environmental changes kill weaker members of the species.
Answer:
A
Selective pressures( Predators, less food etc. ) will cause the less fit variation of a species to decrease in population, causing them not to be able to reproduce. The more fit variation would be able to reproduce more so that over time, the individuals in the species will have the features of the more fit variation.
