When the atom is pulled away only slightly, so that it is still within the attraction curve on the graph, does it move in response to attractive or repulsive forces?
my science class
When pulled slightly, the atom moves in response to attractive forces.
Meaning of potential energy curve::
It is common to find the potential energy curve that explains the bonding of two atoms to form a molecule. There is minimum intermolecular interaction when the atoms are isolated from each other.
Attractive forces:When the atom is pulled away only slightly, so that it is still within the attraction curve on the graph, it moves in response to attractive forces.

Why does wind erode the sand in deserts more than the dirt in forests?
There is less water in forests to keep the soil moist.
The dirt in forests is coarser than the sand in deserts.
Forests have larger rocks than deserts.
Deserts have less plant life to hold the soil in place.
Answer:
I think the answer is D
Explanation:
the tree roots helps to hold the dirt down plus the higher amounts od mositure make the dirt denser
Answer:Wind is a stronger erosional force in arid regions than it is in humid regions because winds are stronger. In humid areas, water and vegetation bind the soil so it is harder to pick up. In arid regions, small particles are selectively picked up and transported.

Use what you know about asexual and sexual reproduction to sort the terms below into the correct column. If the term is related to asexual reproduction, write it in the column on the left. If the term is related to sexual reproduction, write it in the column on the right. If the term is related to both types of reproduction, write it in both columns.
Terms: DNA, male and female, one parent, unique, spores, uniform, traits, egg, and sperm
HELPPP PLEASEE and dont answer something random please actually help
im asking again bc i need help asAPPPPP
Answer: DNA, one parent, spores, uniform are asexual
and male and female, unique, traits, egg, sperm are sexual
Explanation: Sexual reproduction just means combining genetic material from two parents. Asexual reproduction produces offspring genetically identical to the one parent.
Answer:
DNA, one parent, spores, uniform are asexual

What description explains how a flower produces a seed? (2 points)
Group of answer choices
1.After the stamen produces pollen, the pollen is moved to the petal to produce a seed.
2.As pollen travels down the stamen, fertilization occurs and a seed is produced.
3.When the ovule receives pollen, fertilization occurs and a seed is produced.
4.When the stigma receives pollen, a seed is produced and then fertilization occurs.
Answer:
Pretty sure its #3
Explanation:
Plants produce flowers to make seeds. To make a seed a flower must be pollinated. Pollen from the male part of one flower travels to the female part of another flower where the seeds are made. ... The petals act like an advertisement to attract various animals, which will carry the pollen from one flower to another.

Predict what will happen to the concentration of pyruvate, NADH, and H+ when ATP synthase is stopped by oligomycin
The concentration of pyruvate and NADH does not no change, however the concentration of H+ increases.
Oligomycin is a toxic substance to humans, produced by bacteria of the Streptomyces type. It acts by blocking the proton channel in a region of the ATP synthase enzyme, inhibiting oxidative phosphorylation. Thus, the electron transport chain is slowed but not completely stopped.
Cellular respiration consists of a metabolic pathway that breaks down the glucose molecule to produce energy in the form of ATP. Stages of cellular respiration are:
GlycolysisPyruvate oxidationKrebs cycle or the citric acid cycleOxidative phosphorylationGlycolysis consists of the breakdown of glucose to form two pyruvate molecules, where energy is produced in the form of ATP and NADH. Then, pyruvate oxidation occurs, catalyzed by an enzyme called pyruvate dehydrogenase in the mitochondrial matrix. Next, is the Krebs cycle where energy is produced in the form of ATP and other biosynthetic reactions also occur where the intermediates produced are required to make other molecules, such as amino acids, nucleotide bases and cholesterol. Finally, oxidative phosphorylation takes place as a metabolic process that uses energy released by the oxidation of nutrients to produce ATP. It consists of two stages: in the first one, free energy generated by redox chemical reactions in various multiprotein complexes (electron transport chain) and produces an electrochemical gradient of protons (H+) across an associated membrane in a process called chemiosmosis. The respiratory chain consists of three main protein complexes (complex I, III, IV), and several "auxiliary" complexes, utilizing a variety of electron donors and acceptors. The three complexes associate in supercomplexes to channel electron transport molecules, coenzyme Q and cytochrome c, making the process more efficient. So, the proton gradient produced by proton pumping is used to make ATP molecules. Protons move through the ATP synthase down their concentration gradient into the matrix catalyzing the conversion of ADP to ATP.
Then, using oligocycin there will be no change in the concentration of pyruvate since the synthesis of it (from the breakdown of glucose) does not depend upon an ATP synthase. Also, there is no change in the concentration of NADH because it is oxidized and reduced via redox reactions which also does not depend on the enzyme. At last, there is an increase in the concentration of H+ (protons) because its gradient wont be use by the ATP synthase to make ATP molecules.

How is transpiration related to photosynthesis?
1 They are not related, they are two separate processes that do not interact.
2 Transpiration brings water to cells; photosynthesis carries it away.
Photosynthesis creates sugar, and transpiration delivers the sugar and water to the plant roots.
Transpiration delivers water needed for photosynthesis to the cells.
Answer:
Water along with Carbon dioxide are essential for the process of Photosynthesis. Transpiration, the loss of water through stomata creates what is known as the Transpiration pull. This force enables a continued supply of water for photosynthesis, and distribution of nutrients to the plant for growth and maintenance.
Answer:
Transpiration is the loss of water from a plant in the form of water vapor. Water is absorbed by roots from the soil and transported as a liquid to the leaves via xylem. ... water to the leaf cell surfaces where it is converted from a liquid into a gas ... photosynthesis; however, this large opening will also allow the leaf to lose large.
