Species X and Y are not related to humans.
Species Y and Z are not related to humans.
Species X and Z are related to humans.
Species X and Y are related to humans.
Answer:
Species X and Y are related to humans.
Explanation:
The chart shows information about three different embryos early in their development. The best supported by the information in the chart is that Species X and Y are related to humans. Thus, option D is correct.
What is an embryo?An embryo refers to the early development stage with respect to the multicellular organism. The organism should be again produced se-xually. Moreover, the development of embryonic should be a portion of the life cycle just done after fertilization and continued via when the structure of the body is formed like tissues and organs.
The development of embryonic i.e. used for proof with respect to evolution should be related species that contain the same embroys.The similarities during the embryo stage of development among different animals are due to the expression of ancient genes.
These ancient genes have the same evolutionary origin, thereby they are homo-logous sequences. For example, fish embryos and human embryos express certain homo-logous genes in the embryos stage, thereby leading to the development of gill slit during this stage.
Therefore,Thus, option D is correct.

How do the respiratory and circulatory systems work together to make gas exchange possible?Giving brainliest to first right answer
Answer:
Answer: The respiratory system moves air in and out of the body. When you breath in oxygen this creates oxygenated blood. The blood moves through the aorta which then distributes the oxygenated blood to rest of the body. The co2 then leaves the lungs when you exhale. Hope this helped. :)
Explanation:
Answer: [SAMPLE RESPONSE] The two systems work together in several ways. First, the respiratory system brings oxygen in the air to the alveoli in the lungs. The circulatory system then delivers the oxygen to the cells. Second, the circulatory system picks up carbon dioxide from the cells and carries it to the lungs, where it is released when we exhale.

What is brain?
The part the nervous system that contains the cerebrum and cerebellum is the brain. The brain is an organ in the body that controls different other activities in the body. Almost everything in the body is controlled by the brain. The three main parts of the brain is; cerebrum, cerebellum, brainstem. The cerebrum controls speech and emotion, the cerebellum controls movement and the brainstem controls sneezing, coughing.
Spinal cord is a part of the nervous system transports information between the brain and other parts of the body. The spinal cord is a tubular and thin structure composed of nervous tissue. The spinal cord functions are to the transmission of neural signals among the brain and other parts of the body. Spinal Cord is necessary because the brain communicates with the body through it.
Thus, the brain sends information by the spinal cord to the peripheral nerves everywhere to the body that serves to regulate the muscles and inner organs.

Why do land plants need to conserve water
Answer: Some arid-climate plants are able to conserve water because of their reduced leaf size. Less leaf surface area results in reduced water loss through the epidermis. Small leaves have fewer stomata than larger leaves, and that adaptation also reduces water loss.
Which best describes genetic mutations?
A. Some inherited genetic mutations can be good for the offspring.
B. Different genetic mutations cause few forms of cancer.
C. Somatic mutations can be inherited from parents or acquired during life.
D.Genetic mutations that cause diseases are always passed on to offspring.
Answer:
A genetic mutation is a random change in the DNA that is passed on further generations of cells and or organisms. Genetic mutations are accidental changes in the DNA in the germ cells or early in the formation of the embryo.
Explanation:
Some inherited genetic mutations can be good for the offspring.
What is mutation?"It is a change in the structure of a gene."Gene is a structural and functional unit of hereditary.It is caused due to addition, deletion or copying of single base pairs of DNA.The mutation that occurs in somatic cells (cell other than stem cells or s ex cells) are not transferred from parent to offspring.A mutation should occur in s ex cell, in order for it to pass down to the offspring. So, the mutation that cause disease if occurs in somatic cell will not be passed to the offspring.The mutation can sometime result in the production of new proteins that are beneficial in nature.Not all the genetic mutation can cause cancer.Hence, the correct option is A. Some inherited genetic mutations can be good for the offspring.

Select the living organisms that will decrease as a result of the loss of coral in the food web.
Answer:
Butterfly fish, Triggerfish, parrotfish, and sharks
Explanation: Because the first three fish listed feed on coral, their populations will decrease if coral is eliminated because that means there will be less food to go around for the populations to consume. Many will die out. If those fish die, there will be less of them for the sharks to eat, causing the shark population to decrease as well.
Si cruzamos dos individuos homocigotos de cobaya, uno negro y otro blanco, y sabemos que el carácter negro es dominante sobre el blanco. Su descendencia tendrá la siguiente características
Answer:
The offspring will be black because they are heterozygous for a dominant trait that is controlled by monogenic inheritance.
Explanation:
Guinea pigs will be heterozygous because they inherit a dominant allele that encodes for the black color and a recessive allele associated with the white color. Heterozygosity is a genetic condition associated with the presence of two alleles at a locus which are inherited from both parents, one from the mother and the other from the father

What feature is the same in the formation of many sedimentary rocks and fossil fuel?many sedimentary rocks and fossil fuels-
A-require material to be buried and exposed to heat amd pressure.
B-are made out of organic material that stores the sun energy
C-form where there are frequent earthquakes and volcanic activity
D- are produced high in the mountains where temperatures are low
Answer:
maybe C i'm so sorry if this is wrong
Explanation:
Organic materials and silt build on top to produce fossil fuels. Heat and pressure transform organic materials into coal, petroleum, or natural gas. Therefore, option (A) is correct.
What are fossil fuels?An extracted and burnt fossil fuel is a hydrocarbon-containing substance that naturally originated in the Earth's crust from the remnants of extinct plants and animals. Coal, oil, and natural gas are the three primary fossil fuels.
Because certain sedimentary rocks contain trapped fossil fuels, sedimentary rocks and fossil fuels are connected. As organic materials and silt build up on top over time, fossil fuels are created. The organic material undergoes a chemical shift under heat and pressure, turning it into coal, oil, or natural gas.

Write a summary of the pathways rocks can take to become sedimentary, igneous, and metamorphic rocks.
Answer:
When a certain type of rock, specifically, an igneous rock, is deeper into the ground, and it is under the influence of high temperatures and pressures, it will start to change its molecular structure over time. In addition to the high temperature and pressure, chemical influences are also very important, so the the rock will gradually turn into a metamorphic rock.
Depending on the type of influences, and their intensity as well, one type of rock can evolve into multiple different types of metamorphic rocks.
