4 0

Answer:

There are two types of endoplasmic reticulum: rough endoplasmic reticulum (rough ER) and smooth endoplasmic reticulum (smooth ER). Both types are present in plant and animal cells. The two types of ER often appear as if separate, but they are sub-compartments of the same organelle.

I'd say infiltration

Infiltration Definition-When precipitation hits the ground, it has two options depending on where it is in its story line. It may infiltrate the soil or continue across the land as runoff. Infiltration occurs when surface water enters the soil. This process is similar to pouring water onto a sponge.

kari74 [83]

Answer:

1. Height

2. Girth

Explanation:

The woody plants grow in two manners: the primary growth and secondary growth.

The primary growth is considered the type of growth which increases the height of the plant which involves the apical meristem present at the tip of the shoot.

When the height increases up to its maximum length, then secondary growth begins which add tissues to the side that is it increases the girth by adding bark, secondary xylem and phloem.

Thus, Height and Girth is correct.

If all living things are related then where did all their differences come from?
stiks02 [169]

Answer:

<em>Hox </em>Gene

Explanation:

First, you're question is very vital, there are many ways in classifying along with identifying all living organisms that includes; morphological analysis, molecular systematics (studying the similarities and differences of the genetic data such in the sequences of DNA, RNA, and rRNA ), homology, cladistics, etc. based on phylogenetic tree, which the study of the evolutionary among various species.

But through it said that all living organisms shared one common ancestor. However, what makes them different from one to another is the homeotic genes that called <em>Hox </em>Genes; which specify the fate of a particular segment or region of the body, meaning the number and arrangements of the<em> Hox</em> genes varies considerably among different types of animals.

For instance, Sponges have at least one homologous to<em> Hox</em> genes, also insects have nine or more <em>Hox </em>genes resulting in multiple <em>Hox </em>genes occur in a cluster in which the genes are close to each other along a chromosome. Therefore, increases in the number of<em> Hox</em> genes have been instrumental in the evolution of many animals species with greater complexity in body structure.

Overall, more <em>Hox</em> genes, more complexity in body structure resulting in the differences of their morphological structure.

Hope that answered your question!
