Answers

Answer:

Eukaryotic cells contain organelles that are enclosed in membranes. ... Prokaryotic cells contain a nucleus that is enclosed in a membrane

1. A Prokaryotic cell is surrounded by a single membrane layer but In the case of Eukaryotic, there are two surroundings 1. Plasma membrane 2. Nuclear membrane.

2. In the case of prokaryotic cells, the cell wall is made up of Carbohydrates, lipids, protein and certain amino acids whereas The eukaryotic cell wall is made up of chitin and cellulose.

What’s the differences between the three main classes of sponges.

Answers

Answer: There are three classes. These classes include Calcerea, Desmospongia, and Hexactinellida.

(spicules are rod-shaped cellular projections that make up the skeleton of sponges) hope this helps!

They have a negative effect because the herbivores make up almost all of the  natural predator´s diet.

An organism that breaks down organic matter into simpler materials (like carbon dioxide) is called a decomposer. Decomposers absorb nutrients from living things or the organic matter they leave behind. They do not need to kill to get their food. Do your results suggest bears are decomposers? Explain your reasoning.

Answers

Answer:

No, bears are consumers

Explanation:

Both decomposers and consumers are heterotrophic organisms, i.e., they cannot produce their own food. There are four different classes of heterotrophic organisms: decomposers, herbivores, carnivores and omnivores. The decomposers are heterotrophic organisms that return nutrients to the soil from the organisms that break down. Moreover, bears are classified as omnivores (consumers) that need to kill to get their food. These animals obtain nutrients and energy from both plant and animal sources.

Bears are consumers

Explanation:

During the development of human offspring, the fetus begins to hear and see that is in the first option as the fetus is the stage of human development that occurs after the embryonic stage.

What is a fetus?

During this fetal stage, the structures that began to form during the embryonic stage continue to grow and develop, and the fetus begins to hear and see during this stage, as the ears and eyes are formed and become functional, and it also develops many other organs and systems during this stage, including the respiratory, digestive, etc. As a result, the fetus is the stage at which more complex structures develop, and it later develops into the fully mature baby.

As a result, the fetus begins to hear and see during the development of human offspring, which is in the first option because the fetus is the stage of human development that occurs after the embryonic stage.

How does cognition and biology influence learning?

Answers

GREETINGS!

Both Cognition and biology plays role in Conditioning and Learning

Cognitive aspects of learning refer to thinking processes and mental procedures involved in the learning process. Cognitive factors that influence learning range from basic learning processes, such as memorizing facts or information, to higher-level processes, such as understanding, application, analysis and evaluation.

Biological factors also play important role for example Aversion to a particular taste is conditioned only by pairing the taste (a conditioned stimulus) with nausea (an unconditioned stimulus). Generally, taste aversion is developed after ingestion of food that causes nausea, sickness, or vomiting. If taste is paired with other unconditioned stimuli, conditioning doesn’t occur. Another example is Instinctive drift or Instinctual drift. Any behavior is instinctive if it is performed without being based upon prior experience (that is, in the absence of learning), and is therefore an expression of innate biological factors.

Should blue crab fishing in the Chesapeake Bay be banned?

Answers

(This is most likely an opinionated question but this is what I would say)

Blue crabs get their name from their blue-tinted claws and are very popular type of crab. Many people harvest these crabs for meat. The number of blue crabs has decreased in the Chesapeake Bay because of over- harvesting and changes to their habitat. (Then explain if you think it should be banned after knowing this information) if you don’t think it should be banned then you could talk about regulations and licensing for crab fishing, or if you think it should be banned you could explain the effects of habitat loss on the crabs.

Answers

Answer:

When the cell is not dividing, the genetic material is loosely dispersed throughout the nucleus in a threadlike form called chromatin.

Explanation:

Chromatin is the thread-like chromosomes spread throughout the nucleus.

What are chromatin and its functions?Eukaryotic cells' nuclei include a combination of macromolecules called chromatin, which is made up of DNA, RNA, and protein. Heterochromatin (condensed) and euchromatin are the two types of chromatin. The main proteins that make up chromatin are termed histones, which act as bases for the DNA to wrap around to form the "bead-like" structures known as nucleosomes.

A certain chocolate bar contains 6 mg of caffeine in a 1.5 oz. Serving. The king-size version of the chocolate bar is 85 grams. How much caffeine, in mg, would you consume if you eat the entire king-size bar?Fill in the answer in the blank provided. Mg of caffeine

Answers

Answer:

The amount of caffeine that would be consumed if one eats the entire king-size bar will be 11.99 mg

Explanation:

This question can be reframed in the manner below for better understanding.

If 1.5 oz or ounce of a chocolate bar contains 6 mg of caffeine, how many milligrams (mg) of caffeine is contained in 85 grams of the same chocolate bar.

Firstly, the ounce should be converted to grams

If 1 ounce = 28.35g

1.5 ounce = ?

= 1.5 × 28.35/1

=42.53g

Hence, 42.53g of the chocolate bar contains 6 mg of caffeine

85g of the chocolate will contain

42.53g = 6mg

85g = X

where X is the amount of caffeine that will be consumed in mg

X = 85 × 6/42.53

X = 11.99 mg

The amount of caffeine that would be consumed if one eats the entire king-size bar will be 11.99 mg

Gametes produced by an organism contain a combination of genes from that organism. In every gamete, this combination is

A. the same because it is created from the same DNA

B. the same because chromosomes are copied prior lo melosis

C. different due to DNA replication prior to mitosis

D. different due to independent assortment during meiosis​

Answers

Answer:

D). different due to independent assortment during meiosis​

Explanation:

Gametes that an organism produces accommodates a blend of genes of that organism and in each gamete, this blend or combination is 'distinct and that is due to independent assortment during meiosis.' It implies that the chromosomes pass randomly for isolation of poles during the division of cells at the time of the process of meiosis and this independent segregation causes each gamete to contain a unique combination of genetic code. Thus, option D is the correct answer.
