A DNA strand has the sequence ACCGAGCIT. Which is the complementary strand of RNA? OTGGCTCGAA O UGGCUCGAA O GTTAGTGCC CAATCTAGG
Answer:
UGGCUCGAA
Explanation:
UGGCUCGAA. According to the rule of complementarity, in RNA adenine (A) binds to uracile (U), and guanine (G) binds to cytosine (C). So, the DNA sequence is ACCGAGCTT
how the overfishing of a single species, such as the fish eaten by sea lions,
can affect an entire ecosystem.
Answer:
This can cause an extinction in that entire species of animals and sea lions would then resort to something else to eat and if they don’t find food to eat they can starve and so on

Chromosomes determine all inherited traits because they are made up of
A. ATP
B. DNA
C. centromeres
D. phospholipids
Chromosomes determine all inherited traits because they are made up of DNA.
What are the functions of chromosomes?Chromosomes allow DNA to be accurately copied during these cell divisions. So one more time. Chromosomes are found in the nuclei of our cells and allow DNA to be accurately copied during cell division. This ensures that our inner workings proceed smoothly and efficiently.
The main function of chromosomes is to carry the DNA and transfer the genetic information from parents to offspring. Chromosomes play an important role during cell division. They protect the DNA from getting tangled and damaged.
Chromosome are the thread-like structures intermingled with each other in the nucleus. They carry genes that help in the transfer of characters from the parents to the offspring and thus play an important role in the inheritance of characters.

someone please thoroughly explain lac operon and trp operon
Thanks
Answer:
Like the lac operon, the trp operon is a negative control mechanism. The lac operon responds to an inducer that causes the repressor to dissociate from the operator, derepressing the operon. The trp operon responds to a repressor protein that binds to two molecules of tryptophan.

Oc) a trait that helps an individual survive in its environment

d) the ability to survive poisons

e) a common allele found in a successful population
Answer:
c) a trait that helps an individual survive in its environment
Explanation:
Selective advantage is a trait that helps an individual survive better than others in its environment. It stems from the principle of Natural selection that states that individuals have differing abilities to survive due to differences in phenotype.
This trait helps individuals to adapt better to their environments and develop resistance to diseases which they, or weaker individuals around them would have succumbed to. People who have sickle cell anemia, for instance, have developed resistance to diseases.

Which statement best describes the relationship between antigens and antibodies? Antigens cause the lymph nodes to decrease in size, and antibodies cause the lymph nodes to increase in size. Antibodies cause the production of antigens, and antigens attack antibodies. Antigens cause lymph to be clear, and antibodies cause lymph to become yellow. Antigens cause the production of antibodies, and antibodies attack antigens.
Answer:
B: It produces antibodies specific to an antigen.
Explanation:
B lymphocytes (aka B-cells) are lymphocyte white blood cells. They release antibodies that are specifically made for each pathogen and attach themselves onto invading cells and flag it as a harmful cell so that T-cells can come and dispose of it.
If i'm wrong let me know. Hope this helps tho. :D
Answer:
Antigens cause the production of antibodies, and antibodies attack antigens. (D)
Explanation:
From some online research,
1)An antibody is specifically produced in response to an antigen. (Taken from Quizlet)
2)Antibodies bound to antigens on a pathogen's membrane may activate complement proteins to form a membrane attack complex (Taken from a Quizziz)
3)Antigens trigger your immune system to launch an antibody response. This means each antibody wages war against one target antigen. Once antibodies detect antigens, they bind and neutralize them. (Taken from Healthline)
Basically, this means antibodies are formed whenever antigens exist to counter-act it.

Answer:
The nature versus nurture debate is one of the oldest issues in psychology. The debate centers on the relative contributions of genetic inheritance and environmental factors to human development.
Explanation:
Assuming that the three genes undergo independent assortment, predict the phenotypic ratio of the offspring in the F2 generation.
Answer:
The answer is 1:1:1:1:1:1:1:1.
Explanation:
Assuming that the three genes undergo independent assortment, the phenotypic ratio of the offspring in the F2 generation is 1:1:1:1:1:1:1:1.
What are phenotypic traits?The term "phenotype" describes a person's observable characteristics, such as height, eye color, and blood type. Both a person's genomic makeup (genotype) and environmental circumstances affect their phenotype.
According to Mendel's law of independent assortment, the alleles of two or more distinct genes are independently selected into gametes. In other words, an allele for one gene does not affect the allele for another gene that a gamete acquires.
The F1 generation was self-crossed to produce the second filial generation, which is the F2 generation.
Therefore, the F2 generation's offspring have a 1:1:1:1:1:1:1:1:1:1 phenotypic ratio.

Body systems interact with one another to carry out life processes. When we eat food, it is broken down into nutrients that can then be used by body cells for metabolic processes and building cellular structures. Many body systems are involved in this process. Select the body systems that would NOT be involved in the breakdown and utilization of nutrients.
Body organs and systems are assigned different roles and functions for proper working and coordination. Cells need energy for working and growth which is provided by the breaking of food substances by the body systems.
The systems that will not break nutrients are:
Respiratory systemIntegumentary systemReproductive systemThe systems can be explained as:
The digestive and the excretory system are the main systems involved in the digestion, absorption and excretion of food, nutrients and waste in the body.The organs of the digestive and excretory system break the food particles, absorb the essential nutrients and minerals and eliminate the unessential and waste fluid and the solid materials from the body.The respiratory, integumentary and reproductive systems are not involved in breaking, digesting, absorbing or eliminating the nutrients.Therefore, respiratory, reproductive and integumentary systems are not involved in utilizing and breaking nutrients.

2) If the last base in the underlined sequence was changed by mutation to a “C”, how would the protein be changed?
3) If the 4th base in the sequence was deleted by radiation (mutation), how would the sequence be changed?
If the 4th base in the sequence was deleted by radiation (mutation), how would the sequence be changed.
What is Mutation?A mutation is a change to an organism's DNA sequence. Errors in DNA replication during cell division, exposure to mutagens, or viral infection can all cause mutations.
Somatic mutations (which happen in body cells) cannot be passed on to offspring, whereas germline mutations (which happen in eggs and sperm) can.
Our cells are constantly undergoing mutations, yet very few of these have any negative effects on our health. A mutation is never so advantageous in real life that it makes someone a superhero or does anything strange like give them wings.
Therefore, If the 4th base in the sequence was deleted by radiation (mutation), how would the sequence be changed.
