PLEASE HURRY I REALLY NEED HELP BEFORE MY TEST!!!
Answer:
the answer is e on the test
hope this helps
Dwayne is making a cladogram using a diagonal line. He should place the least primitive organism in E. The correct option is A.
What is a cladogram?Diagrams are called cladograms to show the relationships between various taxonomic groups known as "clades." Cladograms reconstruct the taxa's evolutionary history (phylogeny) by showing these relationships. Phylogeny and trees are other names for cladograms.
Using the term "cladogram" emphasizes to some biologists that the diagram represents a hypothesis about the true evolutionary history of a group, whereas "phylogenies" represent true evolutionary history.
A cladogram's root, clades, and nodes are its most important components. The root is the first ancestor shared by all groups that branched off from it.
Therefore, the correct option is A, E.

Use the internet to research genes and their affects on heredity. How many chromosomes do we inherit from each parent? What are recessive and dominant genes? What are inherited traits? What are acquired traits?
Answer:
23 chromosomes
A dominant gene is a type of gene which dominates in the inheritance pattern and masks the other one, on the other hand, a recessive gene is that which does not show its trait in inheritance pattern and hidden by the dominant one. A dominant gene is stronger gene while the recessive gene is a week gene. Dominant gene is always expressed in the upper case letters like A, F, V whereas recessive gene is always denoted by the lower case letters like a, f and v. dominant gene show in the inheritance when one of the two genes is dominant but in case of recessive gene both the genes of a trait should be recessive.
Traits you get from your parents. Inherited features evolve due to genetic material rearrangement and mutation. The parents transfer those traits (inherited) to their offspring. These aren't dying but passed on to the next generation. Example: earlobe attached or free, and curly hair.
An acquired characteristic is a non-heritable change in a function or structure of a living organism caused after birth by disease, injury, accident, deliberate modification, variation, repeated use, disuse, misuse, or other environmental influence. Acquired traits are synonymous with acquired characteristics. They are not passed on to offspring through reproduction.

without oxygen what will brain cells do
Answer:
They will die.
Explanation:
Without oxygen, the brain's cells cannot metabolize glucose, and therefore cannot convert glucose into energy. When your brain is deprived of oxygen, then, the ultimate cause of brain death is inadequate energy to power the brain's cells.
Answer:
Brain cells are destroyed after 4 to 6 minutes without oxygen

how do endangered animals affect the earth?
Answer:
Explanation:
When a species becomes endangered, it is a sign that the ecosystem is slowly falling apart. Each species that is lost triggers the loss of other species within its ecosystem. Humans depend on healthy ecosystems to purify our environment.Do you think that in the human species, there are psychological traits such as empathy, aggression, intellect, imagination, etc. are more common characteristics of one sex rather than another?
Answer:
each sex has these traits, but with some, like aggression, I feel can be more "biased", so to speak, to the male sex

Which of the following is NOT one of the potential mechanisms allowing kin recognition among animals? Group of answer choices kin-differential spatial association, so that kin are reliably found in a given place phenotype matching, whereby kin are identified through comparison of their phenotypic attributes with those learned from reliable kin, including oneself kin-differential familiarization, whereb social familiars are treated as relatives. kin-branding, whereby all individuals are labeled actively by each other at birth so that kin can be discriminated from nonkin. genetic similarity detection, whereby phenotypic labels are correlated with one's underlying genotype, allowing for kin discrimination based on that.
Answer:
The correct answer is "kin-branding, whereby all individuals are labeled actively by each other at birth so that kin can be discriminated from nonkin".
Explanation:
Kin recognition, also known as kin detection, is an ability developed by some animals to detect organisms that are genetic related and discriminate among other animals that are not (nonkin). There are some mechanisms that animals use for kin recognition, however labeling actively each other is not one of them. In most cases, animals use kin recognition based on pheromonal cues.

Which planet is most similar in temperature to Earth?
Answer:
It depends; If you're asking for very temporary moments on the planet, it would be mercury, because its temperature ranges from 427 degrees to -180 degrees Celcius. If you were to stand just in the right spot at just the right time, its temperature would be the same as the earth's temperature.
But if you are asking about longer periods of time, it would be Mars. Its average temperature is around -60 degrees celcius, but its summer can get up to 20 degrees celcius.
I really hope this helped you.

describe the process of building a paradigm and of shifting one
Answer:
Explanation:
A paradigm shift is a major change in the concepts and practices of how something works or is accomplished.
A paradigm shift very often happens when new technology is introduced that radically alters the production process of a good or service.
Although the idea of paradigms has been around for quite some time, the concept was explored by physicist and philosopher Thomas Kahn Kuhn.

Which best describes the role of chlorophyll in energy conversion?
Answer:
Explanation:
Chlorophyll absorbs light and converts it to chemical energy. ... During photosynthesis, plants absorb light energy from the sun and convert it into chemical energy in the form of glucose.
The role of chlorophyll during the process of photosynthesis is that it effectively converts the captured radiant energy (light energy) from the sun to chemical energy.
What is Chlorophyll?Chlorophyll may be defined as the type of green-colored pigment which is present in all green plants, some algae, and cyanobacteria. It is present in the chloroplast of the plant and carries out the entire process of photosynthesis.
This green-colored pigment is generally made up of porphyrin rings with magnesium being the co-factor. A chain of carbon and hydrogen is also present. This is known as the Phytol tail. The function of chlorophyll in each photosynthetic organism remains the same throughout.
Therefore, the role of chlorophyll during the process of photosynthesis is that it effectively converts the captured radiant energy (light energy) from the sun to chemical energy.
