This diagram is an example of which global cycle?
phosphate cycle
carbon cycle
water cycle
nitrogen cycle
The correct answer is Water cycle
Explanation:
The diagram presented shows how water, water vapor and even ice/snow flow from one system of the Earth to another. In this, there are included processes such as evaporation that implies water from water bodies turning into water vapor and going to the atmosphere; transpiration that involves the evaporation from the plants, and precipitation as rain, snow, or similar occur and water returns to the surface of Earth. According to this, the cycle depicted is the water cycle.

An advantage of asexual reproduction over sexual reproduction is that organisms reproduce asexually have greater genetic diversity
Answer:
False
Explanation:
Sexual reproduction produces organisms with more diversity because the offsprings are each different in their own way, unless they are identical twins, while asexual reproduction usually produces offspring that are exactly alike with like variation. The asexual offspring are usually identical to the parent with the exact DNA sequence.
Why leaves float on water
Answer:
because they are very light and they're density is very low
Explanation:
i think thats why
Answer:
Leaves float on water since they are too lightweight to break the surface tension of the water. Leaves also contain chloroplasts; which makes sugars using sunlight (a.k.a. photosynthesis). One of the by-products of this process is Oxygen. The oxygen sits in the middle of the leaf, called the Parenchyma. This gives the leaf a lower density than water; thus causing it to float.

What is the independent variable in the above example?
Answer:
hi shelbi
Explanation:
Since plants are naturally green thanks to the pigment chlorophyll, green light has the least impact on them. Additionally, changing colored light aids plants in achieving various objectives.
What elements make up an experiment's independent variables?
The variable you alter, regulate, or change in an experimental study to examine its effects is known as an independent variable.
It is named "independent" because it is unaffected by any other study variables. Other names for independent variables include: Explaining factors
For instance, blue light promotes the growth of vegetative leaves. Plants can blossom when red and blue light are present together.
The independent variable (height) influences the dependent variable (height).
Therefore, performing an experiment, the independent variable refers to the thing you change, and the dependent variable refers to the thing that changes as a result of that change.

(Q002) Review the vertebral column and individual vertebrae from Exercise 3 (p. 166 of your lab manual). What similarities and differences do you notice between the three major types of vertebrae? Why might these similarities exist? Why might these differences exist? Humans do not have tails, so we do not have caudal vertebrae (the vertebrae that make up the tail). However, many other primates do have these vertebrae. Based on what you know about the other kinds of vertebrae, what would you expect caudal vertebrae to look like? Compare your estimation to images of caudal vertebrae in your classroom, online, or in books. How accurate was your estimation?
Answer and Explanation:
1. The biggest similarity between the main types of vertebrae is the location where they are found since they are all established on the body's back, precisely on the midline of the back. The main differences, on the other hand, are related to the size and weight of each of them.
2. The similarities exist because all the vertebrae have to promote the support of the body, the back being the most appropriate place for them to establish themselves.
3. The differences are related to the function and type of support that each vertebrae promotes, the higher the level of systemization, the larger and thicker the vertebrae must be.
4. The caudal vertebrae should be similar to the vertebrae of the coccix, since a tail would be a representation of elongation of the coccix. We can reach this conclusion through the analysis of images that promote the visualization of this area of the body.

Explanation:
Correctly identify the following situation as an example of positive OR
negative feed back. When blood pressure increases, signals are sent to the
brain from the blood vessels. Signals are sent to the heart from the brain,
and heart rate slows down, thus helping blood pressure to return to
normal. *
1.Positive Feedback
2.Negative Feedback
Answer:
Negative Feedback
Explanation:
Positive feedback is only used to enhance the stimulus. In this case, the blood pressure was sent back to homeostatic levels which means that the stimulus was reversed in order to reach dynamic equilibrium.

how many chromosomes would you have after DNA replication
Answer: Chromosomes are coiled structures made of DNA and proteins. Chromosomes form after DNA replicates; prior to replication, DNA exists as chromatin. Chromosomes contain genes, which code for proteins. Human cells normally have 46 chromosomes, made up of two sets of chromosomes, one set inherited from each parent.
Explanation:
In the diagram below, what part of the excretory system is labeled B?
A-
A. Kidney
OB. Ureter
OC. Urethra
OD. Bladder
B.
D
Option(B) Ureter is the correct option.
The ureter is a vital part of the urinary system in humans. It is a muscular tube that connects the kidneys to the urinary bladder. Each human has two ureters, one attached to each kidney, and they play a crucial role in the transportation of urine from the kidneys to the bladder.
The primary function of the ureter is to carry urine that is produced in the kidneys to the urinary bladder for storage before it is eliminated from the body through urination. The ureters accomplish this by using peristalsis, a wave-like muscular contraction, to propel urine along their length.
The ureters have a complex anatomical course. They originate from the renal pelvis, which is the funnel-shaped structure that collects urine from the kidneys. From there, they extend downward, crossing over the brim of the pelvis and passing behind the peritoneum, the membrane lining the abdominal cavity.
The efficient functioning of the ureters is essential for the proper elimination of waste products and maintenance of fluid balance in the body. Any obstruction or abnormality in the ureters can lead to conditions like kidney stones, urinary tract infections, or urinary reflux.
In summary, the ureters are muscular tubes that transport urine from the kidneys to the urinary bladder. They rely on peristaltic contractions to propel urine, and their structure and positioning help ensure unidirectional flow.

In which of the following scenarios will natural selection most likely occur?
a
Very little genetic variation is present in the species
b
No reproductive barriers present in the area were the species is located
c
A geographical area that has limited food to support the individuals living there
d
Ideal environmental conditions resulting in less competition between individuals
Please Hurry
Answer:
C
Explanation:
There is limited food so only the individuals who can get the food will survive.
Natural selection can be defined as the process of selection of organisms that are better adapted to their environments. It refers to the changing and adaptation in the organisms.
Natural selection is based on the concept of 'survival of the fittest'. The organism that is best adapted to its environment will be 'selected' by nature to survive and thus, pass forward its genes to the future generation.The scenario when there is no genetic variation present there will be no natural selection as there will be no 'fittest' organism. Moreover, the absence of reproductive barriers is bound to allow gene flow between two populations. Natural selection occurs when the conditions are not ideal and genetic variations are present.Thus, it will occur in a geographical area with limited food. Hence, the correct answer is option C.

Explain why the roots of a plant grow in all directions if there is no gravity
Answer:
the reason why roots grow in all directions is because they need to be strong and hold the tree up in all directions.
Explanation:
trees need to be really stable and a really wide base makes it very hard to push it over and also trees can access more water if they have a bigger net of roots so if you have a tree near a stream you will realize that they have a lot of roots headed for the stream.

Separation of suspended particles from a fluid environment to a non-fluid environment through a porous membrane
Answer:
B. Transport of molecules across a membrane from a high to low concentration gradient by means of a carrier protein
Explanation:
According to this diagram showing the presence of certain molecules on one side of the membrane, making their way to the other side across the membrane. Due to the difference in concentration on either side of the membrane, a concentration gradient is formed.
Based on the diagram, the movement or transport of molecules is occurring from a region of high concentration to a region of low concentration. This means that it's a form of PASSIVE TRANSPORT, however, the molecules are being transported across via the aid of CARRIER PROTEINS as depicted in the image.
