The Rio Grande river flows through the South Texas Plains ecoregion of Texas. The river is a major source of water for cities and farms in the area. Sometimes, so much of the Rio Grande's water is used that the river does not reach the Gulf of Mexico. How does the loss of river water affect ocean plants near the mouth of the river? A. Less sediment is deposited in the soil. B. The ocean plants cause more weathering. C. More algae grows and competes for resources. D. The slow water causes more erosion.
Answer:
A. Less sediment is deposited in the soil.
Explanation:
Less sediment is deposited in the soil if there is less amount of water receives by the ocean plants because river water brings minerals with them from passing through the mountains to the ocean. These sediments brings nutrients which are necessary for the ocean plants for their growth and development so we can say that less sediments are deposited in the soil of ocean plants due to less river water.

Compare and contrast the elevated temperature of someone who is exercising vigorously and someone who has an infection
Answer:
Due to muscle contraction and fighting of white blood cells.
Explanation:
Exercise increases the temperature of body because about 20% of the energy produced in contracting muscles is used for muscle contraction while the remaining 80% is converted into heat energy, as a result body's temperature increases whereas a person who has infection also experience high body temperature because the body work faster to fight against the infection that leads to high temperature.
The three states of matter are modeled in the heating curve seen here. Identify ALL of the changes that must take place for a substance to change state, from a solid to a gas
A) Pressure increases
B) Temperature increases.
C) Particles spread apart.
D)Kinetic energy increases.
E) Particle motion increases.
Answer: B, C, D, E
Explanation:
In a generalised manner B, C, D and E takes place for a substance to change state, from a solid to a gas.
What is phase transition?The physical process of changing a medium's state from one to another is known as a phase transition. The phrase is frequently used to describe transitions between the three fundamental states of matter—solid, liquid, and gas—and, in rare instances, plasma.
Heat must be used to provide energy for molecules to go through phase change. The intermolecular connections that keep the substance in its current state are broken using this energy. When the element receives enough energy, the phase change will occur.
Without going through the liquid state, sublimation is the process by which a substance moves straight from the solid to the gas state.

Rapid reproduction is an advantage of which process?
A. gamete formation
B. sexual reproduction
C. asexual reproduction
D. chromosome duplication
Answer:
I believe the correct answer is asexual reproduction because they can reproduce fast, and with multiple offspring. Hope this helped you!
Sexual reproduction in animals depends on the production of gametes.
Which of these processes produces gametes in animals? *
Mitosis
Fertilization
O Meiosis
Binary fission
The process that produces gametes in animals is meiosis.
What is MeiosisMeiosis is a specialized type of cell division that occurs in the reproductive cells, or germ cells, of animals. It involves two rounds of cell division, resulting in the production of four haploid daughter cells, each with half the number of chromosomes as the parent cell.
During meiosis, the genetic material is shuffled and recombined through processes such as crossing over and independent assortment. This genetic variation contributes to the diversity of offspring produced through sexual reproduction.

Answer:
D. 4
Explanation:
Reflection can be defined as a phenomenon which typically involves a change in the direction of a ray of light or waves as it falls on a smooth surface.
Simply stated, reflection occurs when a ray of light or wavefronts bounces off a smooth surface.
From the diagram provided above, the thin beam of light which illustrates reflection is the fourth because as it hit the surface, it bounced back to the medium from which it was originally propagated with.
Scientists took some cells and grew them in a Petri dish with nutrients. After a while, the cells grew to form a thin layer and stopped when they came in contact with other cells. What does this tell you about cells and the cell cycle?
Answer:
Contact inhibition.
Explanation:
Contact inhibition is a response of a cell in which cell growth stopped when it touches or comes in contact with another cell. When the normal and healthy cells grows and touching other cells, the cell receives a red light signal to stop its growth so the cell stop its growth while on the other hand, if there is no contact with other cell the cell continues its growth.

him explain his theory of evolution What did
Darwin mean by the term Natural Selection?
!!pleas help!! :((
Answer:
Resources are limited in nature, organisms with heritable traits that favor survival and reproduction will tend to leave more offspring than their peers, causing the traits to increase in frequency over generations.
Darwin meant this my term 'Natural Selection'
Answer:
He defined natural selection as the "principle by which each slight variation, if useful, is preserved".
Explanation:
Darwin's Theory of Evolution by Natural Selection
More individuals are produced each generation that can survive. Phenotypic variation exists among individuals and the variation is heritable. Those individuals with heritable traits better suited to the environment will survive.

Why are predators the smallest group at the top in the energy pyramid
Answer:
Predators eat prey, technically speaking.
Explanation:
The lowest and largest group takes the most energy cause it's first base. Going up the chain, the second group takes that energy from the first. Then the third, takes the energy from the second and so on. It's a cycle, and the the smallest group at the top of the energy pyramid will be given the less energy that travels throughout the pyramid.
I hope this makes sense.
