1- how does modern technology provide evidence that all organisms have a common ancestor?
2- what new discoveries about evolution have modern technology made possible?
Answer: 1. Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features). Similarities and differences among biological molecules (e.g., in the DNA sequence of genes) can be used to determine species' relatedness.
2. The changes in our behavioral patterns and adaptations that are caused by these technological advances could prove to be the primary driving forces behind the next stage of evolution for our species. These members of the species are more likely to reproduce and pass their genes on to their children.

Choose all of the areas in which the United States invoked the Roosevelt Corollary to the Monroe Doctrine.
The correct answer to this open question is the following.
Unfortunately, you did not attach the options to answer this question.
What we can do to help you is commenting on the following.
Throughout history, the United States invoked the Roosevelt Corollary to the Monroe Doctrine to accomplish some imperialistic and interventionists goals in different Central American and South American countries.
We can set some examples here. For instance, that was the case of the US intervention in the Island of Cuba, in Nicaragua, Dominican Republic, Hati, and the US presence for so many years in the Panama Canal.
Let's have in mind that the Roosevelt Corollary to the Monroe Doctrine was originally called for intervening in Latin American countries that could not pay their debt to European creditors.
The message the US wanted to convey to European superpowers that had interests in this region was that from now on, it was going to be the US business to intervene in the Americas. If Europe tried to intervene, it was going to be understood as direct aggression to the United States.

Natural reseeding uses natural elements and actors to plant the seeds of trees. These elements and actors include water, wind, birds, rodents and other actors capable of scattering seed.
Species diversity is what defines the differentiation between the different species in an ecosystem and Ecosystem diversity relates to how biological communities/ ecosystems can be different from each other based on the organisms and food chains available in each.

My biology curriculum isn't reliable so I need to ask questions here
1 Why is it important for gametes to be haploid?(1 point)
A) It is impossible for them to be diploid because reproduction does not result in diploidy.
B) They fuse to form a diploid organism so there is the correct number of chromosomes.
C) Neither parent has the full set of genetic information so each must contribute their half.
D) When gametes are made, the diploid cell splits twice, creating four haploid organisms.
2 The inheritance pattern of one gene will not affect the inheritance pattern of another gene. This is known as(1 point)
A) crossing over.
B) genetic variation.
C) random distribution.
D) independent assortment.
3 Which of the following is a difference between phase I and phase II of meiosis?(1 point)
A) Genetic variations can only occur during phase II of meiosis.
B) Phase I results in two diploid daughter cells and phase II results in four haploid daughter cells.
C) Phase I results in daughter cells with 23 chromosomes each and phase II with 46 chromosomes each.
D) Anaphase, metaphase, and telophase only occurs during phase I of meiosis.
4 What is heredity?(1 point)
A) the adaptation of certain individuals that increases their likelihood of survival
B) the passing of genetic information from parents to their offspring
C) the random distribution of chromosomes to produce new genetic combinations
D) the exchange of genetic information to create new variation
5 During meiosis, sister chromatids may exchange sections of DNA leading to genetic diversity. What is this process called?(1 point)
A) karyotypes
B) independent assortment
C) nondisjunction
D) crossing-over
1. It is important for gametes to be haploid because: B) They fuse to form a diploid organism so there is the correct number of chromosomes.
2. When the inheritance pattern of one gene doesn't affect the inheritance pattern of another gene, this is known as: D) independent assortment.
3. A difference between phase I and phase II of meiosis is: B) Phase I results in two diploid daughter cells and phase II results in four haploid daughter cells.
4. Heredity simply refers to: B) the passing of genetic information from parents to their offspring.
5. During meiosis, sister chromatids may exchange sections of DNA leading to genetic diversity in a process called: D) crossing-over.
Gametes are also known to as sex cells and they can be defined as the reproductive cells that are found in a living organism.
It is important for gametes to be haploid cells is because when the sperm and the egg fuse to form a diploid organism, the living sex cells will have 46 chromosomes.Independent assortment refers to a biological process through which the inheritance pattern of a particular gene doesn't affect the inheritance pattern of another gene.
During meiosis, two (2) diploid daughter cells are formed in phase I while four (4) haploid daughter cells are formed in phase II.
Heredity can be defined as the transfer of genetic information (traits) from the parents of a living organism to their offspring, either through sexual reproduction or asexual reproduction.
Some examples of hereditary traits are:
Dimples.Baldness.Height.During meiosis, crossing-over makes it possible for sister chromatids to exchange sections of deoxyribonucleic acid (DNA) which leads to genetic diversity.

What is the structure of DNA? 20 points.
Answer:
Basic structure of DNA
DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code.
DNA structure and function
DNA is the information molecule. It stores instructions for making other large molecules, called proteins. These instructions are stored inside each of your cells, distributed among 46 long structures called chromosomes. These chromosomes are made up of thousands of shorter segments of DNA, called genes.
Explanation:
DNA is made up of molecules called nucleotides. Nucleotides are attached together to form two long strands that spiral to create a structure called a double helix. If you think of the double helix structure as a ladder, the phosphate and sugar molecules would be the sides, while the bases would be the rungs.

D. The ground tissue of the root system stores food for later use by
leaves
Answer: A, B, D
Explanation: credit to the comments on the other. I also did the test
The three ways through which a plant's organ systems work together are as follows:
The shoot system delivers food to the root system.The root system delivers materials from the soil to the shoot system. The ground tissue of the root system stores food for later use by leaves.Thus, the correct options are A, B, and D.
How do plants deliver water and nutrients to other parts?Plants deliver water and other nutrients to other parts with the help of vascular tissues like xylem and phloem.
Xylem transports water, nutrients, and other minerals from the soil to all parts.
Phloem mediates the migration of foods from the leaves to the rest of the plants.
The shoot system delivers food to the root system via the vascular tissue phloem. The root system delivers materials from the soil to the shoot system via the vascular tissue Xylem.
The ground tissue of the vascular plant is responsible for storing the carbohydrates constructed by the plants and utilized by the leaves when required.
Therefore, the correct options are A, B, and D.
