Answer:
E. climax
Explanation:
The point of equilibrium in a community is not something that happens very often in nature, in fact it is relatively rare, but there are several examples that have shown how this works. When an equilibrium is reached in a community, it is basically a community consisted of dominant, prominent, small number of species that manage to create a stable community. The state of equilibrium is also known as a climax community. This type of community appears when there's a situation in which the web of biotic interactions between the organisms becomes so intricate that there's simply no way that another organisms can be admitted into the community.

Answer:
the answer is B)
Explanation: I had this question in my health class lol
Answer:
B. A sperm cell fertilizes a vertebrate's egg cell, creating a zygote.
Explanation:
Not A, because it is showing asexual production, in which, when the pollen lands, it will grow without needing of an opposite gender.
Not C, because it is exactly the same as A, in which it promotes asexual production.
Not D, because while sexual reproduction is needed, it does not give the process, rather, the process of life after being borned (you want an answer that gives the process before birth.

Imagine that you live in Maine. Currently there is a high pressure area over Maine. If a low pressure are moves in, how will the direction of the wind change ?
Answer:the wind will move towards the low pressure area
Explanation:this happens by a basic principal called diffusion ,liquids and gases (matter in which molecules are greatly spaced ) tend to move towards low pressure area so the wind molecules will flow towards low pressure area.
(True or false) Whale sharks and manta rays are very large predators and are a danger to divers?
(True or false) octopus always remain the color that they were when born?
(True or false) the sex of baby turtles is determined by the temperature of the sand they incubate in?
(True or false) some corals produce both sperm and eggs?
1. False
Whale sharks and manta rays can indeed be large, and they are predators, but they do not pose threat to divers. Both of these species, even though they do not look alike at all, are part of the shark family. While they are both in the predator category, they actually eat miniature organisms and very tiny fish in general, thus not being anywhere near as aggressive or dangerous for the divers as some of their shark relatives. The manta rays for example do not even have teeth to pose a significant threat, they have a poisonous sting on their tail but that is only used for defense, not attack.
2. False
The octopuses are definitely one of the weirdest and most interesting animals on the planet. They are highly intelligent, have even been noticed using tools, have three hearts, one central and eight other independent brains in their tentacles, and also have a beak. Like all of that is not weird enough, they also have the ability to change their color, and not just the color all over, but also to mimic certain patters. The change of color is used for both camouflage for attack and for defense and avoiding predators.
3. True
The turtles spend the majority of their lives in water, but they still use the land for nesting. They will come to the sandy beaches, dig a large hole, and fill the hole with hundreds of tiny eggs, and than cover them with send. The sex of the turtles that are developing in the eggs depends directly on the temperature of the sand, so it can literary be a situation where all of them will be female because of the temperature, or all of them to be male because of the same reason.
4. True
The corals are a weird bunch. They look like plants, but they are actually animals. They also look like one compact unit, but they are actually millions, or billions miniature animals that are collaborating and build colonies. They also are interesting in their reproduction, as all of the species are able to reproduce asexually, but there are some that are able to reproduce both asexually and sexually, depending on the circumstances.
Which of the following best describes how comparative anatomy can be used to determine the evolutionary relationship between two organisms?
Organisms that have a great deal of physical similarity are more likely to share a common ancestor than two organisms with few physical traits in common.
Comparing the physical traits of two organisms makes it possible to determine how long ago they shared a common ancestor.
Studying the physical differences between two organisms will show which organism evolved from the other.
Two species that have few physical traits in common do not share a common ancestor and most likely evolved from different species.

Which of these mass movement events is considered
A) creep
B) rock avalanche
C) slump
D) rock fall
Rock avalanche is a mass movement event that is considered a slide. The correct answer is B.
Rock avalanche is a large landslide from rock slopes. It travels farther than smaller events. Rock avalanche rarely occur but they are very catastrophic events that can result into huge fatalities.
Further ExplanationRock avalanche is very dangerous being the most deadly of all landslides events. It is a deep seated rock that is made up of rapid break up of failed rock mass with high velocities and long run-outs.
Rock avalanches became known in 19th century in Switzerland. It was first recognized in Switzerland when the Elm and Goldau events killed several people that are even far away from the origin of the slide.
The Elm and Goldau events in Switzerland revealed Rock avalanche possesses some peculiarities. Both events entail volumes of cubic meters that engaged large amount of energy and the distance covered in both events is very long.
After these catastrophic events, all rockslides that relates to these characteristics are classified as large rockslides, rock avalanche or “sturzstorms”.
Rock avalanche always result in high number of fatalities in developing countries. However, landslide is triggered by heavy earthquake, heavy rainfall and many other natural causes.

How is energy expended in active transport?
A. Glycolysis
B. Lysic acid
C. ATP
D. Krebs cycle
Answer:
The correct answer is ATP.
Explanation:
When molecules or ions moves into higher concentration from lower concentration through a cell membrane with the help of enzymes and requires energy, this type of transport of molecules or substances called active transport. Active transport requires chemical energy to perform this transport and ATP is the form of chemical energy expended in this process. ATP is an abrevation of adenosine triphosphate.
ATP is the energy expended in active transport.
Active transport is the homeostatic process that requires energy to move particles across the plasma membrane.
Further Explanation Transport in living organismsPlants and animals use various processes to transport materials from one point to another.There are classified as either passive transport or active transport.Active transport It is a type of transport in living organisms that involves movement of substances against a concentration gradient through the plasma membrane.Active transport is the homeostatic process that requires chemical energy to move particles across the plasma membrane.The chemical energy used during active transport is in the form of ATP.Passive transportIt is a type of transport that does not involve the use of energy to aid movement of substances in living organisms.Passive transport involves free movement of substances and through special types of transporters or carriers.Types of passive transport includes; simple diffusion, facilitated diffusion, osmosis, and mass flow among others.Types of passive transportFacilitated diffusionFacilitated diffusion is a type of passive transport which involves the diffusion of solutes by use of transport proteins in the plasma membrane.Facilitated diffusion uses transport proteins to transport solutes down their concentration gradient.Osmosis Osmosis is a special diffusion that involves the movement of water molecules from a region where they are highly concentrated to a region where they are lowly concentrated through a semipermeable membrane.It may also refer to the movement of water molecules from a region of low particle concentration to a region of a high particle concentration.Diffusion Diffusion is a type of passive transport that involves movement of particles from a region of high concentration to a region of low concentration.Diffusion involves movement of molecules of substances other than water.Keywords: Active transport, energy in the form of ATP, Passive transport, Diffusion, Osmosis,

which of the following statements is true about external and internal fertilization?
A. external fertilization doesn’t require sexual intercoure
B. all animals that lay eggs use extra large fertilization
C. internal fertilization doesn’t require sexual intercourse
D. all animals that lay eggs use internal fertilization
Answer:
A is correct external fertilisation doesn't require sexual intercourse
Fertilization is defined as the fusion of male and female gametes. The fertilization can be internal or external depending on the organisms and environmental conditions.
The correct answer is:
Option A. external fertilization doesn’t require sexual intercourse
The external and internal fertilization can be explained as:
Internal Fertilization:
Internal fertilization is the process in which egg and sperm cells are united to form a zygote.It takes place inside the female body and follows the mode of sexual reproduction. It gives rise to young offspring similar to the parent. Examples are humans, monkeys, dogs, and other mammals.
External Fertilization:
External fertilization refers to the fusion of gametes outside the female's body.Aquatic organisms like frogs and fish undergo external fertilization. The organism lay eggs in the water, where the sperms released fuse with the female gamete to give rises to the organism. The external fertilization is triggered by the temperature and length of the day.
Thus, external fertilization does not require sexual intercourse, as it takes place outside the female body.

chemicals used in chemotherapy treatments to fight cancer can also harm cells in hair follicle and bone marrow what characteristic do this cells most likely share with cancerous cells
A:they form tumors
B:they spread through the blood
C:they dive rapidly
D: they contain a mutation
Like cancer cells, they divide rapidly and grow fast.
The answer would be C.
Answer:
C - they divide rapidly
Explanation:
The patient diagnosed with cancer may, at some point, undergo chemotherapy and, although not having the real size of treatment, already reaches the doctor's office aware that the approach is accompanied by some consequences, such as hair loss, infections, fever. and vomit.
These side effects of chemotherapy are the result of medications, which directly interfere with the ability of cells to multiply, normal or tumor, and vary according to the type and dosage of medications. In each person, the reactions may be different, varying in frequency and intensity.
Like cancer cells, hair follicle cells and bone marrow cells can divide rapidly, so these cells are affected by chemotherapy.

Answer:
It’s B
Explanation:
A dog weighs 70 N on Earth. If the dog was sent to Moon, how would it's weight change
Well first use the equation w=mg so if he is 70N you plug that in for w. The gravity on eartg is 9.8. So 70=m(9.8) m= 7.14
Now on the moon the gravity is 1.6m/s sooooo use the mAss u previously found and plug it in. 7.14(1.6)=w w= 11.42 so the weight changes on the moon and earth but the mAss remains the same.
Final answer:
A dog that weighs 70 N on Earth would weigh approximately 11.60 N on the Moon due to the lower acceleration due to gravity there, which is about one-sixth of Earth's gravity.
Explanation:
If a dog weighs 70 N on Earth, its weight would change significantly if it were taken to the Moon. This change occurs because the acceleration due to gravity on the Moon is only about 1.625 m/s², which is much less than Earth's 9.80 m/s². To calculate the dog's weight on the Moon, you would use the formula:
Weight on Moon = Mass x Acceleration due to gravity on the Moon
The dog's mass (which remains constant regardless of location) can be found by dividing its weight on Earth by Earth's gravity:
Mass = Weight on Earth / Acceleration due to gravity on Earth
Mass = 70 N / 9.80 m/s² ≈ 7.143 kg
Now, multiply this mass by the Moon's gravity:
Weight on Moon = 7.143 kg x 1.625 m/s² ≈ 11.60 N

After a plant is set on a windowsill for several days, its owner comes back to find its stem bent at a sharp angle toward the glass of the window. Which of the following describes this movement of the plant in response to stimuli?
A. Gravitropism
B. Negative phototropism
C. Positive phototropism
D. Thigmotropism
Answer:
C. Positive phototropism
Explanation:
This is a response of plants towards external stimuli. The plant is bent toward the glass of the window because light is coming from the window. It is considered as positive phototropism because it is moving towards the light. The opposite occurs with negative phototropism. In negative phototropism, the movement of plant would be away from the external stimulus.
When you talk about gravitropism, this is the direction of the growth of plants that is affected by gravity. Thigmotropism is the growth response of the plant towards physical touch.
