The opossum, which is native to North America, and the kangaroo, which is native to Australia, are marsupials.
The fact that both these mammals incubate their immature offspring in a pouch provides evidence that they -
O are descended from a common ancestor
O belong to the same species
O must range great distances to eat
have very similar skeletal structures
Answer:
Belong to the same species
Explanation:
Marsupials carry their young in "pouches", and are therefore related to other marsupials, like the kangaroo, opossum, wombats, and koala to name a few.
The opossum is a native of North America as the kangaroo is a native to Australia and both of them are mammals thus boh belong to the same specie. Thus option B is correct.
What are mammals?A mammal is an animal that is warm-blooded and has hair, vertebrates, and backbone. These creatures share human relations and produce milk for their young ones. The kangaroo is like an opossum that is marsupials carry their young in "pouches".

A biologist pollinates a true-breeding yellow flower with pollen from a true-breeding red flower of the same species. All of the F1 offspring are yellow. What question can be answered with the F2 cross?
Answer:
See the answer below
Explanation:
The question that can be answered with the F2 cross would be if the yellow flower color is dominant over the red flower color in the species. In other words, whether the inheritance of flower color follows a simple Mendelian inheritance or otherwise can be answered.
Assuming that the inheritance of the flower color follows the Mendelian pattern, the red flower trait would re-emerge among the F2 offspring and the ratio of yellow to red flower offspring would approximately be equal to 3:1. Otherwise, a more complex pattern of inheritance would be involved.

PLEASE HELP Select from the drop-down menu to correctly complete the statement. Different types of cells within an organism 1.All are the same 2.Serve a different function 3.Can survive on their own 4.Do not have any function
Answer:
The correct answer is - 2. Serve a different function
Explanation:
In a multicellular organism there are different type of the cells present and termed and differentiat on the basis of their specific function in the body or the location in the body. The different type of cells present are epithelilal cell, nerve cells, connective tissue cell and muscle cell. These cells can be further divided on their function as well such as cardiac cell, hepatic cell, nephron cells and neurons and many other cells.
All these specialized cell peroform their own function in the body such as nephrons helps in blood purification, hepatic cells help in various functon include synthesis of bile and hormones and metabolism. Cardiac muscles made up of cells that helps in puming the blood and mainataining blood flow.

Artificial selection has produced a wide variety of crop plants, livestock, and pets. Which characteristic of artificial selection makes it different from natural selection
Answer:
Genetic Problems
Explanation:
When people genetically modify animals, they can mess up a lot of their natural abilities. For example in some cases scientist have made cows who produce more milk, but couldn't reproduce anymore because of it. Sometimes it even hurts the animal. People have bred dogs in certain ways that makes it hard for them to breathe, like Bull dogs who has respiratory issues. This makes decreases their life span and continuing to bred them will only make it worse. When scientist have a certain trait they want they also make animals breed with their own families. Incest creates a lot of genetic problems.

A mutation that could be inherited by offspring would result from-?
Answer: Along with substitutions, mutations can also be caused by insertions, deletions, or duplications of DNA sequences. Some mutations are hereditary because they are passed down to an offspring from a parent carrying a mutation through the germ line, meaning through an egg or sperm cell carrying the mutation.
Explanation:
A mutation that could be inherited by offspring would leads from a base substitution in gametes during meiosis. The correct option is D.
What is mutation?Any alteration to a cell's DNA sequence. Alterations in cell division can result in specific mutations.
As can exposure to environmental DNA-damaging substances. Mutations may be negative, positive, or ineffective.
Errors in DNA replication during cell division, exposure to mutagens, or viral infection can all cause mutations.
Somatic mutations (which happen in body cells) cannot be passed on to offspring, whereas germline mutations (which happen in eggs and sperm) can.
A base substitution in gametes during meiosis would result in a mutation that might be passed on to progeny.
Thus, the correct option is D.

(AKS 4c, DOK 3) Which explanation below accurately describes the
relationship between photosynthesis and cellular respiration?
Photosynthesis uses water and carbon dioxide in the presence of light to create
sugars with a by-product of oxygen. These sugars are used by the organism in the
presence of oxygen to make energy (frequently ATP) that can be used in cellular
processes with a by-product of water and carbon dioxide.

presence of oxygen to make energy (frequently ATP) that can be used in cellular
processes with a by-product of water and carbon dioxide.
Explanation:
photosynthesis= water+CO2+light energy --> sugar + oxygen
cellular respiration is the exact opposite equation except you use ATP energy in place of light energy
The relationship between photosynthesis and cellular respiration is that Photosynthesis uses water and carbon dioxide in the presence of light to create sugars with a by-product of oxygen. These sugars are used by the organism in the presence of oxygen to make energy (frequently ATP) that can be used in cellular and processes with a by-product of water and carbon dioxide.
What is photosynthesis?Photosynthesis is known as the process in which the green plants prepare their own food in the presence of sunlight and heat energy converted into chemical energy in the process of photosynthesis and green plants prepare their own food so they are known as the autotrophs.
