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.

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.

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.

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

Answer:
Carbon cycle, neutral and decomposition
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
