Do mutations always lead to evolution? (1 point)
A. O No, because some mutations happen in body cells, so they are not passed on.
B. No, because most mutations lead to death of the organism.
C. Yes, because mutations create adaptations that give a competitive advantage.
D. Yes, because there would be no change in populations without mutations.
Answer:
B
Explanation:
Mutations are a way different option from the original genomes, a mutation is a change within the genes and can mostly lead to the death of organisms. But only MOST of them lead to death which is why B is correct.

How can evidence from an experiment be explained in relationship to the hypothesis?
as a prediction
as a question
as an inference
as a conclusion
The relationship to the hypothesis can be explained using a conclusion, i.e., option D is correct.
What is a hypothesis?A supposition explanation is formed based on limited evidence as a starting point for further investigation is referred to as a hypothesis.
A conclusion correlates the facts to the hypothesis, although inference is an expert assumption.
A conclusion explains facts and supplies the reader with less information than an inference.

What's function of ADH
ADH is the Antidiuretic hormone. This is a brain hormone that induces the kidneys to discharge less water, resulting in less generation of urine.
Arginine vasopressin is another name for ADH. The hypothalamus in the brain produces this hormone, which is then stored in the posterior pituitary gland.Vasopressin is a hormone that promotes vasoconstriction and water reabsorption in the renal tubules of the kidney.The amount of water in the blood is constantly regulated and balanced by ADH.Higher water concentration raises the volume and pressure of the blood. Water metabolism is maintained by osmotic sensors( to sense the osmotic pressure) and baroreceptors(to sense the blood pressure) in conjunction with ADH.ADH deficiency often results in an unusual water metabolism condition called diabetes insipidus. A reduction in either the generation of ADH by the hypothalamus or the release of ADH from the pituitary gland is the major causal factor of diabetes insipidus.Excessive urination( polyuria) is a common symptom of this disease, followed by intense thirst, known as polydipsia.To learn more about the ADH, refer to:-

Background: You will be the evolutionary biologist, and complete the following activities
to build a cladogram of Xenites. Based on the order of the rock layers in which fossils
were found, species A appears to be the oldest and probably the most primitive.
1. Fill in the table noting which species of xenite has each characteristic, marking each
yes or no. (3 points)
Observing each of the animals shown we have to classify what each one of them has that differs from the other in this way, the evolutionary process of each one is:
Xenite A: Have eyestalksXenite B: Have eyestalks and mouthXenite C: Have eyestalks, tail and mouthXenite D: Have spine and eyestalksXenite E: Have spine, eyestalks and mouth.What is evolutionary process?Evolutionary processes aim, therefore, to generate greater adaptation of species in an environment. This concept of adaptation is related to several other evolutionary processes, mainly speciation, when new species of organisms are formed from gradual changes in preexisting species.

What is genetic variation in plants??
Answer:
Individual differences or population differences are referred to as genetic variations.
Explanation:
Individual differences or population differences are referred to as genetic variations. Plant breeders can use genetic variability/diversity to improve cultivars with desired qualities and generate new cultivars with both farmers- and breeder-preferred traits (yield potential, early maturity, good shapes, taste, color, extended shelf life, easy to prepare) (disease and pest resistance). Plant breeders and local farmers have harnessed natural genetic variability to boost their yield. GA plays a crucial part in the alleviation of poverty as the population grows. Plant breeders benefit from population variation because it allows them to explore the source and develop new cultivars. Mutation, hybridization between incompatible kinds or introgression, wide-hybridization, and recombination could all be used to accomplish this. Mutation, natural selection, environmental diversity, genetic drift, migration, and population size all have an impact on genetic variability.
Answer:
Gene variation in plants often occurs as the result of gene flow. Pollen is dispersed from one area to another by the wind or by pollinators over great distances. Examples of genetic variation in animals include albinism, cheetahs with stripes, snakes that fly, animals that play dead, and animals that mimic leaves.

Which of the following equations represents the right chemical process that occurs in photosynthesis? Question 8 options: A) Six molecules of carbon dioxide plus six molecules of water plus light energy converts six molecules of oxygen plus sugar. B) Six molecules of oxygen plus six molecules of water plus light energy converts six molecules of carbon dioxide plus sugar. C) Six molecules of water plus six molecules of hydrogen plus six molecules of oxygen converts light energy plus sugar. D) Six molecules of carbon dioxide plus sugar plus light energy converts six molecules of carbon and six molecules of oxygen.
Six molecules of carbon dioxide plus six molecules of water plus light energy converts to six molecules of oxygen plus sugar, Thus, the correct option is A.
What is photosynthesis?Photosynthesis is the process through which plants use sunlight to create their own nourishment. Through a sequence of reactions, light energy from the sun is turned into chemical energy, which is then stored in the form of food.
In the presence of sunlight, 6 molecules of carbon dioxide (CO2) and 6 molecules of water (H2O) react to form 1 molecule of glucose sugar. During photosynthesis, 6 molecules of oxygen are formed in addition to glucose.
The following is a balanced chemical reaction for photosynthesis:
Sunlight
6CO2 + 6H2O —---------> C6H12O6 + 6O2.
(carbon (water) (glucose) (oxygen)

1. According to the stability-diversity hypothesis, why are tropical rain forests stable communities?
Obecause they have high species richness
Obecause they have extreme climates
Obecause they have very little rainfall
because they have low species richness
According to the stability-diversity hypothesis, tropical rain forests are stable communities because they have high species richness. Thus, the correct option is A.
What is Species richness?Species richness may be defined as a count of the number of species living in a community at a particular time.
The tropical rainforest has a stable climate with moderate rainfall. So, species richness and diversity have been found in this biome.
