Answer:

The stigma, a female structure which collects pollen and passes it to the ovary

Explanation:

<u>The structure represented by the letter A in the diagram is the stigma.</u>

The <u>stigma of a flower represents part of the female reproductive structure</u>. The surface of a mature stigma is sticky and as such, it is able to attract pollen grains from the anther. A pollen that lands on the stigma germinates and its pollen tube grows through the style of the stigma down to the ovule where one of the sperm cells of the pollen fertilizes the egg cell of the ovule to form a diploid zygote and the other sperm cell fuses with the polar nuclei of the ovary to form a triploid cell that eventually becomes the endosperm.

<em>The sepal and the petal are labeled as D and C in the diagram respectively while the stamen is made up of B and H.</em>

How is the types of venation in a plant related to the types of root it has and the number of cotyledons in its seeds?​

dicotyledonous

Explanation:

The veinlets form a network in the leaf lamina that is why the type of venation reticulate meaning network. So all dicots have dicotyledonous seeds, a tap root system and leaves with reticulate venation. ( with some exceptions of dicots having parallel venation in leaves like Calophyllum)

daser333 [38]

Given what we know, we can confirm that the statement in the question is in fact true, by the end of the eighth week, the embryo is only 1 inch long and weighs just 1 gram.

<h3>What else do we know about the embryo in this time frame?</h3>

During the first eight weeks, the embryo undergoes many changes. At this time:

  • The legs and arms have formed.
  • The fingers and toes are beginning to develop.
  • It begins to be called a fetus.
  • It is developing the lungs and lymphatic system.
  • and much more.

Therefore, we can confirm that the statement that by the end of the eighth week, the embryo is only 1 inch long and weighs just 1 gram, is in fact true.

An atom has an atomic number 17 and atomic mass number 35. How many neutrons are present in its nucleus?
Pie

Answer:

B. 18

Explanation:

An atom, which is the smallest indivisible particle of matter, further contains certain particles called SUB-ATOMIC PARTICLES namely: proton, neutron and electron. In a neutral/uncharged atom, the number of proton is equal to the number of electrons. The number of protons in an atom represent its ATOMIC NUMBER.

However, the sum of the proton number and neutron number gives the MASS NUMBER i.e. mass no. = proton no. + electron no.

Hence, according to this question which states that an atom has an atomic number of 17 and a mass number of 35. The neutron no. can be calculated as follows:

Neutron no. = mass no. - proton no.

Neutron no. = 35 - 17

Neutron no. = 18
