Answers

Answer: The 3.9 billion year old rock has undergone three half-lives (3.9 divided by 1.3 = 3). After 3 half-lives, 12.5% of the potassium-40 remains undecayed.

Many plants have the ability to respond to herbivores. Some plants produce substances
which are distasteful or toxic in response to an herbivore attack. Which of these is the LEAST correction description of the plant system interactions involved?

A. Carbon dioxide diffuses through stoma into leaf tissues, where it is fixed into organic compounds
which may serve as building blocks for chemical defenses.

B. Root systems obtain water and key minerals from the soil where they are transported to the affected site.

C. Shoot systems carry carbon dioxide, water and nutrients from leaves directly to the affected
plant part, where chemical defense molecules are produced.

D. Chemicals found in a herbivore's saliva trigger chemical messengers which trigger production of
defense molecules

Answers

Answer:

I'm pretty sure that the answer is d :)

Explanation:

Answer:

yeah

Explanation:

Mechanical Defenses

The first line of defense in plants is an intact and impenetrable barrier composed of bark and a waxy cuticle. Both protect plants against herbivores. Other adaptations against herbivores include hard shells, thorns (modified branches), and spines (modified leaves). They discourage animals by causing physical damage or by inducing rashes and allergic reactions. Some Acacia tree species have developed mutualistic relationships with ant colonies: they offer the ants shelter in their hollow thorns in exchange for the ants’ defense of the tree’s leaves.

If embryos share a common structure, what does that say about their evolutionary relationship?

How would the protein sequence of two closely related species compared to the protein sequences of two unrelated species? Give an example of each here.

Answers

Answers:

blank: Homologous

why?: They all have similar structures passed on from a common ancestor. Although they all have different functions now, they still all have the same basic pattern of bones.

blank: Analogous

why?: Butterflies and bats are both unrelated organisms but they both have similar structures. However, unlike homologous structures, analogous structures do the same job (help the organism fly) but are structured entirely differently because they evolved in the two species independently and did not share a common ancestor.

blank: Homologous

why?: (see question 1 ^)

blank: Vestigial

example: An example of a vestigial structure is a human's tail bone.

why?: Over time humans evolved and our tail bones shrank as we adapted. While we still have one, it serves no purpose in our lives today.

blank: Embryology

why?: Embryology is the branch of science and medicine that is focused on the development and study of embryos. Scientists in this field study the prenatal development of gametes, fertilization, and development of embryos and fetuses.

answer: They share a common ancestor

why?: Embryos of many different species can show evidence of sharing a common ancestor based on the similarities and structures of them all. Similar structures during development support common ancestry. For example, all vertebrae embryos develop gill slits and tails but not all develop into those structures. Over time as organisms evolved their structures changed with them.

answer: If the protein sequence of two species is closely related the two species are most likely similar, but the protein sequences of two unrelated species are not similar meaning these two species are very different. By comparing the positions of amino acids on protein chains you can determine how similar the species are. The less different the positions are, the more alike and related they are.

why?: For example, humans and chimpanzees only have one position on the amino acid chain where they are different but if you compare humans and moths there are 31 different positions.

Glycolysis, or the breakdown of glucose, is a process used by almost all organisms as a way to release energy stored within glucose molecules. This energy can then be stored in cells as ATP, which powers cell processes when needed. What does this show, in terms of the evolutionary history of cells using glycolysis?

Answers

Answer:

It was one of the earliest metabolic pathways.

Explanation:

The evolutionary history of cells using glycolysis shows that It was one of the earliest metabolic pathways which is used by nearly all of the organisms on earth for the production of energy for the survival, growth and development. The first organisms used this pathway for the generation of energy and with the passage of time, new pathways are also formed as the organism evolved so we can conclude that glycolysis is the first pathway used by the earliest organisms.

What is true about two different cell types in the body?

Answers

Answer:

Option B

Explanation:

In cell differentiation, the objective is to differentiate cells based on their functions and the organs they are going to form. In this exercise, the cells need to get on and off to define the type of the cell and its function. Hence options A, C is important for cell differentiation. Information from DNA is transferred to mRNA for cell differentiation; hence option D is also correct. While option B has no role in cell differentiation loss of DNA segment could cause mutation i.e. deletion.

Hence, option B is the correct answer
