Which evolved first, photosynthesis or cellular respiration?
Answer:
Because photosynthesis is a source of oxygen, it seems intuitive that photosynthesis evolved first: once enough O2 was in the air, then respiration would be able to arise in the newly oxygen-enriched atmosphere. However, some biologists have argued since the 1970's that respiration in fact evolved first.

Explain how selective breeding can lead to some sheep overheating from having too much wool
Answer:
Selective breeding increases the frequency of favorable gene combinations associated with a particular phenotypic trait
Explanation
Selective breeding, also known as artificial selection, is a method for improving phenotypic traits in plants or animals by mating individuals with specific desirable hereditary traits and then select offspring that have better performance for these traits. This technique is effective only when the parental population used for selection exhibits genetic variability for the trait to be selected. The sheep's wool is a quantitative trait, i.e., a phenotypic characteristic that depends on the cumulative effects of many genes and the environment. In this case, the artificial selection will consist of obtaining sheep with increased production of wool, which is achieved by selecting favorable gene combinations for improved trait performance.

A rhizoid is a rootlike structure of nonvascular plants that is usually one cell thick.
What are non-vascular plants?Non-vascular plants may be defined as those plants that lack a vascular system consisting of xylem and phloem and possess simpler tissue for the conduction of water transport.
A rhizoid provides an anchorage and the capability to absorb nutrients from the soil to the plants.

student wants to view live organisms less than 1 millimeter in size, which are found in a water sample collected from a stream. Which microscope would be best for the student to use while observing these living organisms?
1.) dissecting
2.) compound
3.) scanning
4.) transmission
Answer; I’m guessing the second choice.
Explanation:
Because she said she wants to observe it while it’s still living my guess is compound light microscope don’t take my word on it though, just a guess ...
The type of microscope that would be best for the student to use while observing these living organisms is the compound microscope. Thus, the correct option for this question is B.
What is Microscope?A microscope may be defined as a type of laboratory instrument that is utilized in order to examine objects or specimens that are too small to be observed by the unaided eye.
A Scanning electron microscope is used to visualize the object or specimen which is approximately 500 nm in size. While transmission electron microscope is used to analyze objects which are approximately 1 nm in size.
Now, according to the question, the size of a living organism that a student wants to observe is less than 1 millimeter in size. So, she requires to utilize a compound microscope with utmost priority.
Therefore, a compound microscope is a type of microscope that would be best for the student to use while observing these living organisms. Thus, the correct option for this question is B.

blood can receive Rh+ or Rh-blood.
blood can receive Rh-blood.
Answer: An Rh+ person can receive Rh+ or Rh-. An Rh- person can only receive Rh- blood
Explanation: the Rhesus (Rh) group has three types, CDE. Of these, only the D locus is of general importance, and this is the one involved when we talk about Rh+ or Rh-. The D allele is dominant and DD or Dd are the Rh+ type, while dd is Rh-.
Rh- people have an immune response to the D and produce antibodies which causes blood clots and this can be life-threatening. Some Rh- people have anti-D antibodies in their blood, but the level is too low to affect Rh+ people transfused with Rh- blood. This is also unlikely because Rh+ is by far the more common type.
A particular problem arises when a mother is Rh- and the father Rh+ because the baby may be Rh+. If this happens the mother will produce antibodies to the foetus’s blood which will kill it if they cross the placenta. This is avoided by giving the mother Rh immunoglobulin injections during pregnancy which switch off anti-D antibody production.
It is rare for the C and E loci to cause a significant immune response.
Answer:
Rh+

Rh-
