Schizocoelic development

The coelom is a fluid-filled body cavity, where the internal organs are suspended in. It is the cavity between the wall of the body and the digestive tract.

In the schizocoelic development of the embryo, the coelom, called the schizocoel, develops as a split in the mesoderm. The outer layer of the mesoderm attaches with the ectoderm to form a body's musculature, while the inner layer attaches with the endoderm to form the wall of the digestive tract. 

This type of development is commonly found in annelids, arthropods, and mollusks.

OPTIONS:

a. When there are just two other people at the party.

b. When everyone is wearing a nametag.

c. When there are more than 50 people attending the same party.

d. When the need for help from the person who is having a heart attack is very clear

Answer:

c. When there are more than 50 people attending the same party.

Explanation:

Bystander effect is a term used in social psychology to describe the tendency of an individual to intervene in the event of an emergency to offer help to the person needing it, when others are present at the scene of the emergency.

In the case of an emergency just like the scenario stated in the question, where someone develops a heart attack at a dance party, if the party has more people, the slimmer the chance of the person getting help from any of the 50 people at the party, as the presence of others would tend to discourage the any individual from attempting to help the victim having the heart attack.

The situation that would more likely show the bystander intervention effect is <em>"c. When there are more than 50 people attending the same party."</em>

You are holding a coarse-grained crystalline rock with a texture that can be best described as having "interlocking crystals". t
dusya [7]

This rock can be classified as: an igneous rock.

Igneous rocks are made up of randomly arranged interlocking crystals and the important minerals that can be found in igneous rocks are feldspars, quartz, olivines, pyroxenes, amphiboles, and mafic minerals. All of these minerals are important in the formation of almost all igneous rocks, and they are basic to their classification.

g Choose the correct answer from the list. Group of answer choices DNA sequences that are deduced by comparing many related DNA
REY [17]

Answer:

Explanation:

Group of answer choices DNA sequences that are deduced by comparing many related DNA sequences are called CONSENSUS. Unlike DNA synthesis, RNA synthesis requires TRANSCRIPTION. PROMOTERS direct RNA polymerase to the initiation site. RNA synthesis complexes containing DNA, RNA, and polymerase perform TRANSLATION. RNA synthesis (tRNA, mRNA, and rRNA) takes place in complexes containing DNA, RNA, and polymerase are called TRANSCRIPTION BUBBLES. The expression of beta-galactosidase requires the induction of operons by addition of REPRESSORS.

Look at the data related to honey bee population losses between 2006 and 2013 (Figure 1). Expand on the data. How would you revi
olga_2 [115]

In order to improve the graph and make it more detailed in order to get a better perception why the honey bee populations are decreasing, there's few things that can be added.

- Number of bee keepers over the period

The number of the honey bee colonies is directly connected as to how many bee keepers there are. If there's a trend of a decline in the bee keepers, than there will be a trend in the decline of the honey bees.

- Area of trees suitable for the honey bees

The trees are crucial for the honey bees to be able to produce honey, thus it is very important that they have a certain area of trees on which they can feed upon. If there's a decline in the number of trees for the bees, than the bees will be dying from starvation.

- Pollution

The honey bees are animals that are very sensitive to changes in the environment, especially when it comes to pollution. If the levels of pollution are increasing in areas where there's honey bees, it will certainly affect their numbers in a negative manner.

Two unlabeled slides are viewed under a microscope. Slide A has cells with a visible nucleus, mitochondria, a cell membrane, a c
Travka [436]

Answer:

C. Slide A, plant cells; Slide B, animal cells

Explanation:

The slide A has some organelles that are unique to plant cells, and are mostly found in plant cells. Organelles such as a cell wall and chloroplasts are unique features of plant cells. They are normally absent in animal cells.

Therefore, slide A, which has these cell organelles can be rightly labelled as "plant cells", while side B, which has these organelles missing, can be labelled as "animal cells".
