Answer:
They are nonlobed, simple leaves and are attached oppositely on the branch.
Explanation:
A dichotomous key is a tool you use in biology to know the identity of things in nature such as trees,flowers, fish or even rocks. This key has choices that follow each other in a progressive manner, where one choice led to the other until you identify the item.In this case, to identify Dogwood, you follow the below steps;
1b. Broad leaf = Step 2
2b. Simple leaf = Step 7
7a. Leaf bases attached opposite each other on branch = Step 8
8b. Leaves not lobed = Step 9
9b. Leaves not heart shaped = Dogwood
The key is (1b,2b,7a,8b,9b)
Answer:
The answer is C
Explanation:
Because the earth's surface is made up of different types of land and water, it absorbs the sun's heat at different rates. One example of this uneven heating is the daily wind cycle.
Answer:
Scanning electron microscope.
Explanation:
It is scanning electron microscope because it is an electron microscope that produces image with three dimensional structure of the specimen by scanning the surface of the specimen using beam of electrons that is been focused causing an interaction between the electrons and atoms of the specimen which send signals that indicates information about the specimen.
When a nucleus divides by mitosis, all of the information from the nuclear
chromosomes is passed on to the daughter cells.
Mitosis is a cell division process that results in the formation of two daughter cells during growth processes and in the replacement of worn-out tissues in the body.
The cells produced must have all the information as the cells replicated
have specialized functions which must be passed from parent cells to the daughter cells.

Answer:
The correct answer to the question: For this individual, select the pair of recombinant genotypes that could result if crossing over occurs between these two chromosomes, would be, 3. Ab and aB.
Explanation:
During meiosis, the copy and distribution of genetic information present in genes, and which happens when chromosomes are divided and then crossed over, is a pretty unique one.
Essentially, genetic recombination happens when genes cross over and combine with genes present close to them. This process does not always happen and it is the reason why we say that some gametes are parental, instead of recombinant; because the genes in the chromosomes, especially depending on factors like distance between them, do not combine.
In this particular case, given the way that genes will cross over and knowing how recombination works, we could say that the possible genotypical recombinants for AB on chromosome 1 and ab on chromosome 2 would be the ones offered in option 3.
