Answer:
I think producers
Explanation:
In an energy pyramid, producers have the most energy available. The correct option is 2.
What is energy pyramid?A graphic that depicts the biomass or bioproductivity at each trophic level in an ecosystem is called an ecological pyramid.
An ecosystem's energy transfer from one trophic, or feeding, level to the next is depicted by an energy pyramid.
The model is a figure that contrasts how much energy different trophic levels of species use. Kilocalories are the units used to measure the energy in an energy pyramid (kcal).
The producers are located in the base of the pyramid, which is also its greatest level.
The amount of energy diminishes and the levels get smaller as you progress up the pyramid, via the trophic levels to primary, secondary, and tertiary consumers.
Thus, the correct option is 2.

How are genes and proteins related?
O A. One gene codes for one protein.
B. Genes and proteins are both made of DNA.
C. Both are made from amino acids.
O D. Proteins are made of parts of genes.
Answer:
A.
Explanation:
Most genes contain the information needed to make functional molecules called proteins. (A few genes produce other molecules that help the cell assemble proteins.) The journey from gene to protein is complex and tightly controlled within each cell. It consists of two major steps: transcription and translation.

What most likely caused the difference in the apparent size of the Moon in photographs A and B?
Answer:
Option C
Explanation:
I think it is C distance changed
The distance from the earth to moon changed is most likely caused the difference in the apparent size of the Moon in photographs A and B.
What is Moon?One of the solar system's most recognizable objects is the Moon. Due of its closeness to Earth, it has enormous cultural value and is crucial to the regulation of the planet's tides.
The Moon has essentially little atmosphere, thus it cannot retain heat or act as a surface insulator.
The Moon's surface reaches 127°C in full sunlight, which is far over the boiling point of water. High temperatures last for 13 and a half days, followed by 13 and a half days of darkness.
Therefore, The distance from the earth to moon changed is most likely caused the difference in the apparent size of the Moon in photographs A and B.

A student used poster board to construct this model of DNA.Which statement describes this model of DNA?
Answer:
The model is inaccurate because the base pairs are incorrect.
Explanation:
The model of DNA that the student made was:
G-G
A-A
T-T
C-C
G-G
A-A
T-T
C-C
The model is pairing the bases incorrectly since guanine (G) forms a base pair with cytosine (C) and adenine (A) with thymine (T). In other words, the bases do not pair with the same type.
The DNA strands, which have deoxyribose, phosphate groups, and different bases, are together thanks to hydrogen bonds between the pairs. The pair G-C has three hydrogen bonds, while the pair A-T has two hydrogen bonds.

Which of the following biological activities best demonstrates water's adhesive properties?
Choose 1 answer:
A leaf's cuticle, or waxy over coating, repels water droplets.
B
Water travels through vascular tissue from the roots to the leaves of a plant, moving against
the force of gravity.
Water evaporates from leaves through openings called stomata, which open and close in
response to environmental conditions.
D
The vacuole of a plant cell swells as water enters and dilutes its contents.
Answer:
b
Explanation:
water's hydrogen bonds allow it to move upwards against gravity through plant veins.
B. Water travels through vascular tissue from the roots to the leaves of a plant, moving against the force of gravity.
Adhesion refers to the attraction of water molecules to other molecules other than itself. This is opposed to cohesion (water to water molecules attraction). Adhesion and cohesion are the two properties of water that makes it possible for plants to pull water from the soil.
Roots absorb water from the soil via the root hairs. These water molecules ADHERE to the surfaces of vascular tissue called XYLEM and are transported from the roots to the leaves of a plant, moving against the force of gravity. This process occurs due to the ADHESIVE PROPERTY OF WATER.
Therefore, the ADHESIVE PROPERTY of water allows it to travel through vascular tissue (xylem) from the roots to the leaves of a plant.

Where would you expect precipitation to occur
I think the answer is clouds.
Precipitation is any type of water that forms in the Earth's atmosphere and then drops onto the surface of the Earth. Water vapor, droplets of water suspended in the air, builds up in the Earth's atmosphere. Water vapor in the atmosphere is visible as clouds and fog.
answer:
Precipitation is most abundant where air rises, and least abundant where it sinks. It also tends to be greater near oceans and lakes, and in higher elevations.

There are four phenotypes: tall, short, round, wrinkled
Let us say that for the high trait, tall dominates over short. For the shape trait, round dominates over wrinkled. This is:
T allele determines tall plantst allele determines short plantsR allele determines rounded seedsr allele determines wrinkled seeds.The fact that parental are dihybrid, tells us that their genotypes were TtRr

Imagine I planted a seed in the ground and a tree grew. Explain where all that matter came from?
Answer:
The mass (increasingly bigger size) of a tree comes from the soil. Which makes sense, right? After all, we are taught that plants need soil (enhanced “dirt”) to grow. According to Michigan State University Extension, problems typically arise when asked to explain why there isn’t a big hole around a tree. If the tree is using soil, then there must be less soil around it. But studies show virtually no difference in the amount of soil in a pot when a seed is planted from the amount of soil in the same pot when the plant from that seed is harvested. So where does the mass come from?
The mass of a tree is primarily carbon. The carbon comes from carbon dioxide used during photosynthesis. During photosynthesis, plants convert the sun’s energy into chemical energy which is captured within the bonds of carbon molecules built from atmospheric carbon dioxide and water. Yes, the carbon from carbon dioxide in the air we breathe out ends up in “food” molecules (called glucose) each of which contains 6 carbon atoms (and 12 hydrogen atoms and 6 oxygen atoms).
Explanation:
So the mass comes from the soil but its primarily carbon. HOPED THIS HELPED YOU!

How are flowers and fruits connected?
When a grain of pollen reaches the stigma, it creates a pollen tube for the sperm to journey down the style and fertilize the ovule; fertilized ovules become seeds. Fertilization is the death of the flower, as the petals drop or wither at this point and the ovary starts to enlarge and ripen into what we know as fruit

Which event happens during mitosis of an animal cell?
A. The cell divides its nucleus into two new nuclei.
B. The cell grows larger in size to prepare for duplication.
C. The cell produces structures, such as centrioles, to help with the division.
D. The cell replicates its DNA, which results in the formation of chromosomes.
Answer:
B
Explanation:
because During mitosis, a eukaryotic cell undergoes a carefully coordinated nuclear division that results in the formation of two genetically identical daughter cells.
During Mitosis, a cell undergoes division to form two genetically identical offsprings. Here, the cell grows larger in size to prepare for the duplication. Thus, the correct option is B.
What is Mitosis?Mitosis is also known as equational division. This type of cell division occurs in all types of cells. Here, the genetic content remains constant from parents to their offsprings.
In this type of cell division, a cell undergoes nuclear division (karyokinesis) followed by cytoplasmic division (cytokinesis) which produces genetically and phenotypically identical daughter cell.
The cell first grows in size during the interphase G1 phase, after this the DNA undergoes duplication to increase the nuclear content. This takes place in the S-phase of cell division. After this, in M-phase the cell starts dividing to form daughter cells.
Therefore, the correct option is B.
