The secondary xylem is produced by the cambium. It is placed between the cambium and the medulla. Option B is correct. Secondary xylem.

<h3>What is the secondary xylem?</h3>

The secondary xylem is the tissue that proceeds from the vascular cambium activity.

Its cells are orientated in different ways composing the vertical/axial system and the horizontal/transversal system.

The secondary xylem is essential to the tree growth in high because of its resistance and the capacity to transport water long distances.

Secondary xylem functions are to transport water and minerals through its vessels and tracheids, to provide support and resistance to the plant, and to store reserve substances.

In the cross-section of the adult tree trunk,

The outermost layer that interacts with the environment is called periderm (Brown Layer).

The second layer that follows the periderm is the phloem (Layer C).

The next layer is the cambium (lateral meristem), which produces phloem cells and xylem cells (Layer B).

The secondary xylem follows the vascular cambium (Layer A), and

The medulla is located in the centre of the trunk.

Letter A indicates the <u>secondary xylem</u>.

1. Look at the illustration in Figure 25-4. Do you think that the bud on the side of the adult hydra

Answer:

A. No, because budding is a type of asexual reproduction.

Explanation:

Asexual reproduction is the process where an organism makes a copy of itself by itself. It does not require a mate to make offspring.

The offspring are genetically identical to the parent.

Budding is a type of asexual reproduction where a small outgrowth of the parent breaks off to become a new organism.

Embryo development is usually only discussed in the context of sexual reproduction, where two gametes fertilize one another and a new organism that is genetically different to either parent is formed.

WHOEVER ANSWERS FIRST GET A BRAINLY!!!!Provide a reason why no 2 communities are ever the same. Support your answer with an exam

Advocard [28]

Answer:

No two communities are the same because each one has something specific to them whether it is house structure, rules of the community, how big the community is, and the people that live there.

Explanation:

A great example of this is Weston, FL and Pembroke Pines, FL. In Weston you will find higher class people living there such as celebrities and athletes. The best community to use as a comparison is Botanica Weston. There are mansions in that neighborhood along with many sport icons living there. In Pembroke Pines, it is more of a family based city. In the community Pembroke Falls, you will see more family type houses and a large clubhouse with a pool, game room, and event room to host parties in. Each community has a different identity and no two communities are the same.

Part a - identifying the processes of replication, gene expression, and recombination this activity requires that you correctly

I found the exercise on the internet with the images and brief descriptions. Attached is an image of it.

To the DNA replication bin:
-Image of one cell dividing into two cells, and the mother cell has its DNA being unfolded and replicated.
-"DNA -> 2DNA (copying one DNA molecule to make two identical DNA molecules)"

To the <span>gene expression bin:
-Image of only one cell with some arrows within it indicating the gene expression flow: DNA -> mRNA -> protein
</span>-"DNA->mRNA->protein"<span>
-"transcription"
-"translation"

To the </span><span>recombination bin:
-Image with two cells being one the donor and the other one the recipient. The recipient has DNA with different colours pretending to represent that its DNA has different origins.
-"transformation"
-"conjugation"
-"transduction"</span>
