what happens after point A in regard to the population and resources available at that point in time?
Answer: there are enough available resources for the population
Explanation: the resources and the population is steady however over time the population increases in which there will be not enough resources. I hope this helped I’m doing the same thing lol :)))
In Point A, with regard to the population and resources available at that point in time, the populace has access to ample resources.
What is a population?The term “population” refers to all citizens who are either permanently residing in a country or who are just passing through. This indicator reveals how many people typically reside in a certain area.
Growth rates are the population changes that occur each year as a result of births, deaths, and net migration. The resources and the population are stable, but as the population grows, fewer resources will be available.
Populations can include but are not limited to, individuals, animals, organizations, structures, buildings, cars, farms, objects, or occasions.
Therefore, in Point A, the population has access to enough resources given the population and resources available at that time.

Describe one way that burning rain forest trees affects nutrient cycling differently than cutting them down and leaving them on the forest floor.
Burning trees releases co₂ in the atmosphere, but cutting down trees falling on the ground nutrient returns to the land. Plants which is falling down decomposes and nutrient return to the soil.
How do trees affect the nutrient cycle?Deforestation affects the nutrient cycle because plants are the storage site of many nutrients. The nutrient cycle is interconnected with plants most of the nutrient is directly absorbed by the soil.
Plants absorb nutrients from the soil, and the animal takes nutrients from the plants, when an animal dies its body decomposes in the soil again nutrient dissolve in the soil.
Burning plants releases stores of nitrogen, carbon, and sulfur these create a loss in biodiversity and affect the nutrient cycle.
Therefore burning rainforest affects the nutrient cycle by releasing nutrient components in the atmosphere, so cutting down does not affect

How does sound travel ? How does the medium the sound travels through help determine the speed of sound ?
The speed of a sound wave depends upon the medium through which it travels. In general, sound travels faster through solids than through liquids or gases. Also, the denser the medium, the slower sound will travel through it. The same sound will travel at a different speed on a cold day than it would on a warm day.

Support the following claim: All primates have a common ancestor. use multiple lines of evidence (anatomical, DNA, and embryological evidence) to support the claim. compare the value of each type of evidence, and explain which type of evidence is most valuable for determining evolutionary relationships.
Evidence such as similarity in DNA make-up, embryological and anatomical similarity shows that primates share a common ancestor.
What are primates?Primates are mammals which belong to the order primates.
Primates have unique features such as:
prehensile five-digit hands and feetpossession of flat nails instead of claws acute vision with depth perception due to forward-facing eyesPrimates include man, monkeys, chimpanzee, etc.
The primates share a common ancestor as their anatomical structure are similar with hands and feet.
Embryologically, they are similar too and they share over 90% of their DNA in common.
Based on value, the DNA evidence is the most supportive of common ancestors as the DNA determines the other features of the primates.
Therefore, evidence such as similarity in DNA make-up, embryological and anatomical similarity shows that primates share a common ancestor.

D. Venus fly-trap
Answer:
a algae
Explanation:
it lives there in the ocean
Of these organisms, algae would most likely live in a intertidal zone.
How does algae survive in intertidal zone?Any organism that lives in the intertidal zone must be able to tolerate powerful waves and variations in moisture, temperature, and salt. Sea stars, snails, seaweed, algae, and crabs can be found in the intertidal areas of rocky shorelines. Many brown algae in the intertidal zone have alginic acid in their cell walls, which acts as a water-absorbing gel and prevents the algae from drying up during low tides. In environments with high nitrogen levels, intertidal macroalgae can also outgrow seagrasses. In certain situations, certain algae can be a nuisance. The blue-green algae, also known as cyanobacteria, are ephemeral in their growth and recurrence. They can form mats or filaments and are encrusting.learn more about intertidal zone here: https://brainly.com/question/1346004

The sample is then looked at under a microscope again. what happened to the red blood cells after the sugar was added to the solution?
A- The red blood cells released water through osmosis. The release of water helped the blood cells take in more sugar for energy.
B- The red blood cells absorbed water through osmosis. The absorption of water helped the blood cells take in more sugar for energy.
C- The red blood cells released water through osmosis. The release of water helped the blood cells keep a similar concentration of solutes as the outside solution.

3) a species of dark green trees is spread over a very large terrain. over a long period of time, mountains form in this area and the trees became split by the new formation. later, the trees on the east side of the mountain are all light green.
Over time, the light green and dark green trees spread to a new field that is not separated by the mountains. both types of trees are seen in the same field. however, the trees cannot produce any fertile offspring together. which of the following provides the best explanation as to why the two populations of trees cannot produce fertile offspring?
A- the trees on the west side of the mountain retained their original phenotype that became unique to their population
B- the trees on the east side of the mountain developed a new phenotype, which made them unable to produce fertile offspring.
C- the trees on the east side of the mountain experienced many genetic mutations and recombinations unique to their population
D- the trees on the west side of the mountain could not adapt to the new barrier, which made them unable to produce fertile offspring.
The red blood cell will have released water in order to equalize concentrations on either side of the membrane.
Why did the red blood cell release water?The red blood cell in question was placed in a hypertonic solution. This means that the solute concentration outside the cell is higher than that of it's inside concentration. This mean that through the process of osmosis, the cell will release water in an attempt to dilute the outside concentrations and achieve a balance. This will likely cause the cell to decrease in volume.
Therefore, we can confirm that the red blood cell will have released water in order to equalize concentrations on either side of the membrane.
