-Will give brainliest-
Answers
Answer:
The sugar molecules thus formed contain carbon, hydrogen, and oxygen: Their hydrocarbon backbones are used to make amino acids and other carbon-based molecules that can be assembled into larger molecules (such as proteins or DNA), used for example to form new cells.

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.
Answer:d.

Should blue crab fishing in the Chesapeake Bay be banned?
Answers
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.
In 2003 a disease called SARS was a major concern for health officials. SARS is a very contagious respiratory disease. People were infected by SARS in several countries.

Which two of the following correctly describe what a gene is?
A packet of genetic information that can be passed down from one generation to the next
A DNA molecule
The entire collection of genetic information in a given species
A section of DNA that provides instructions for building a specific protein
I'm not sure
Answers
Answer:
A section of DNA that provides instructions for building a specific protein and A packet of genetic information that can be passed down from one generation to the next
Explanation:
A DNA molecule is not a gene, it is a nucleotide. The entire collection of genetic information in a given species results isn't a gene although many genes comprise what is the genome. Given that those two answers are not what genes are, the other two options are correct.
Engineers tasked with building a car bumper need high-quality plastic that is readily available. They found the material polycarbonate, which is long-lasting and not too costly. Which is one technological design criterion they have already met? be available be attractive be durable be safe
Answers
Answer:
be durable
Explanation:
From the scenario described the Engineers have met one of the main criteria which is for it to be durable. A design needs to be made with a material that is available, durable, and cheap in order for it to be as efficient as possible while also selling and being profitable. By finding the material polycarbonate they have made sure that the design will be durable as well as cost-efficient since the material is "not too costly". Now if they are able to acquire the material in large quantities then they would have met the availability criteria as well.

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.Functions of chromatin:DNA packagingTranscription regulationChromatin and DNA repair

7. Endocytosis and exocytosis do not occur in prokaryotic cells but Endocytosis and exocytosis takes place in many protists and in animals
8. The nucleus is absent in prokaryotic cells. nuclear material lies in the cytoplasm and is called a nucleoid, contains a single chromosome whereas Well developed nucleus found in Eukaryotic cells which surrounds why nuclear membrane nucleus contains two or more chromosomes
9. Fertilization, gamete formation and meiosis do not occur in prokaryotic cells whereas Fertilization, gamete formation and meiosis are well developed in Eukaryotic cells.

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.
