Describe what happens to water particles when ice metls.
Answer:Ice melts when heat energy causes the molecules to move faster, breaking the hydrogen bonds between molecules to form liquid water. In the melting process, the water molecules actually absorb energy.
Explanation:
In a plant species, the allele for dark green leaves (D) is dominant over the allele for light green leaves (d). A plant with Genotype (Dd) is crossed with a plant with genotype (did). What percentage of the offspring are expected to be hybrid for the leaf color trait. A 0% B 25%. C.50%. D 75%
The percentage of the offspring that is expected to be hybrid for the leaf color trait is 50%. The correct option is C.
What are alleles?The trait is caused by a pair of two alleles on the chromosome, and there are two possible outcomes. The dominant allele, which is typically written in capital letters and will control the organism's phenotype even in the presence of the other allele, is the one that has the ability to silence the other allele.
It is used in biology to refer to inherited traits that do not manifest in the phenotype of the individual who possesses them but may do so in their offspring.
Recessive alleles, which are only expressed when they are homozygous, are this other type of allele. Both heterozygous and homozygous genotypes exhibit the dominant allele.
Dd is crossed by dd.
100 / 2 = 50%.
Therefore, the correct option is C.

Answer:
Atom, smallest unit into which matter can be divided without the release of electrically charged particles. It also is the smallest unit of matter that has the characteristic properties of a chemical element. As such, the atom is the basic building block of chemistry.
Atom: has equal number of +ve charge (protons) and -ve charge electrons and hence atom has charge.
Neutrons (having no charge) and protons are present in nucleus. Electrons keep revolving around the nucleus in different shells.

What molecule is used as energy to directly fuel cellular processes like movement, growth and reproduction?
Answer: Energy
Explanation:
Energy. The glucose molecules serve as fuel for cells: their chemical energy can be harvested through processes like cellular respiration and fermentation, which generate adenosine triphosphate— ATPstart text, A, T, P, end text, a small, energy-carrying molecule—for the cell's immediate energy needs.

A group of plant eating animals moves far away from their original population. In the new environment, the only edible vegetation grows at the top of tall trees. In order to survive, the animals need a new adaptation. Which of the following variations would be the most useful new adaptation to members of the group?
A) Wider, flatter teeth that can chew and grind plant material.
B) A longer neck to reach the vegetation that is high up in the trees.
C) A better digestive system for breaking down plant material.
D) Larger ears and eyes located on sides of head to detect predators.
Answer:
B
Explanation:
The others would not help because the animals could not reach the vegetation.

what are the helpful measures to conserve human energy??
Answer:
Adjust your day-to-day behaviors
Energy conservation can be as simple as turning off lights or appliances when you do not need them. You can also use energy-intensive appliances less by performing household tasks manually, such as hang-drying your clothes instead of putting them in the dryer, or washing dishes by hand.

Sea otters regulate the presence of the sea urchins and thus, kelp is regulated for all organisms in the ecosystem. They help to keep enough kelp for other wildlife to feed on. Also, due to their ability to absorb carbon dioxide, the kelp aid in mitigating climatic change and also reduce erosion by reducing the speed of water at the coast.However, if there were too many sea urchins and no sea otter to regulate their production, the kelp would reduce and thus with no food in the ecosystem, it would collapse. As a result, the sea otter protects the kelp forests by checking the local sea urchin population. The sea otter is an example of a
Answer:
keystone species
Explanation:
The sea otter is an example of a keystone species in the scenario.
A keystone species is an organism that has a significant influence on the functioning of the entire ecosystem. Without this species, the ecosystem would either cease to exist in total or entirely different in structure. In other words, a keystone species is a fastener that holds the ecosystem together.
In this case, the sea otter indirectly regulates kelp for all organisms in the ecosystem by directly regulating the presence of sea urchins. Without kelps, several ecosystem functions such as climate change mitigation and erosion reduction would cease. Thus, the sea otter is playing a significant role as a keystone species.

James examines a cell from an aloe plant and a cell from an owl feather. Which structure is found only in the cell from the aloe plant?
O A. chloroplast
OB. membrane
O C. mitochondrion
O D. nucleus
The chloroplast will only be found inside the Aloy plant while other structures will be shared by both cells. Option A is correct.
Difference between Plant and animal cells:Both plant cell animal cells are eukaryotic cells, but both have some unique structures.Plants have a cell wall but animals just have a cell membrane.A plant cell has a chloroplast for photosynthesis while an animal cell does not have a chloroplast.Since owl is an animal and Aloy is a plant
Therefore, the chloroplast will only be found inside the Aloy plant while other structures will be shared by both cells.
