According to the diagram how are the three components
of a nucleotide important to the structure of DNA?
Answer:
A nucleotide of DNA is made up of three parts: a nitrogenous base, a 5-carbon sugar, and a phosphate group. The four nitrogenous bases in DNA are adenine, cytosine, guanine, and thymine.
The phosphate group linked with deoxyribose sugar to make the framework for the nitrogenous bases. The phosphate group and sugar molecule make the DNA backbone and support it. These backbones hold nitrogenous bases and make a monomer of DNA. Nitrogenous bases make DNA stable and hold both backbones together. These bases also make DNA functional.

Which statement correctly describes a feature of the rock cycle?
O Rocks are preserved through the process.
O Rocks change from one type to another.
O Different rock groups are not related to one another.
O Rocks change from one type to another in a specific order.
Answer:
The correct description of a feature of the rock cycle is:
O Rocks change from one type to another.
Explanation:
Sedimentary, metamorphic, and igneous rocks are the three main rock types. Together, they form the universal rock cycle. A sedimentary rock, for example, can change from its known state to another state by passing through crystallization, metamorphism, erosion, and sedimentation. There are no specific orders for the change. The processes that they pass through determine the resulting type.
Answer:
Rocks change from one type to another.

During mammalian embryogenesis, the first differentiation event that occurs leads to a polarization of the outer cells of the 16-cell morula. This outer layer of cells forms the trophectoderm and the inner, apolar clump of cells become the inner cell mass. The inner cell mass will give rise to:
Answer:
the entire embryo
Explanation:
The trophectoderm refers to the polarized single cell layer that forms the wall of the blastocyst, thereby forming the first epithelium during embryogenesis. Moreover, the blastocyst is composed of 1-an inner cell mass (ICM) which will form all the tissues of the embryo's body, and 2-an outer layer composed of cells collectively called the trophoblast. The ICM of the blastocyst will form the embryoblast (which subsequently will give rise to the embryo itself) and the fetus, while the trophoblast will form all of the supporting tissues (i.e., amniotic sac, placenta, and umbilical cord). In humans, the blastocyst is the developmental stage of the embryo on day 5 after fertilization.
The difference in the chromosome arrangement during meiosis in the metaphase plate can lead to greater genetic diversity in a population. Explain your answer
Explanation:
Like mitosis, meiosis is a form of eukaryotic cell division. However, these two processes distribute genetic material among the resulting daughter cells in very different ways. Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell. In contrast, meiosis gives rise to four unique daughter cells, each of which has half the number of chromosomes as the parent cell. Because meiosis creates cells that are destined to become gametes (or reproductive cells), this reduction in chromosome number is critical — without it, the union of two gametes during fertilization would result in offspring with twice the normal number of chromosomes!
Apart from this reduction in chromosome number, meiosis differs from mitosis in yet another way. Specifically, meiosis creates new combinations of genetic material in each of the four daughter cells. These new combinations result from the exchange of DNA between paired chromosomes. Such exchange means that the gametes produced through meiosis exhibit an amazing range of genetic variation.
Finally, unlike mitosis, meiosis involves two rounds of nuclear division, not just one. Despite this fact, many of the other events of meiosis are similar to those that occur in mitosis. For example, prior to undergoing meiosis, a cell goes through an interphase period in which it grows, replicates its chromosomes, and checks all of its systems to ensure that it is ready to divide. Like mitosis, meiosis also has distinct stages called prophase, metaphase, anaphase, and telophase. A key difference, however, is that during meiosis, each of these phases occurs twice — once during the first round of division, called meiosis I, and again during the second round of division, called meiosis II.

birth defects due to radiation are a concern also. why is a fetus especially at risk?
Of the babies that survive, however, few will have birth defects related to the exposure, regardless of how much radiation they were exposed to. Large radiation doses to the fetus during the more sensitive stages of development (between weeks 2 and 18 of pregnancy) can cause birth defects, especially to the brain.

How is mitosis different in plants and animals?
Answer:
The main difference is cell plate formation and how they form the daughter cells during cytokinesis. In plants, they lack centrosomes. A new cell plate will form between the daughter cells for the future cell wall. In animal cells the cell membrane will rather constrict to separates the parent cell into the daughter cells. Plants also do not undergo cell furrowing, unlike animals cells.

How can embryos be more useful than adults to show evolutionary relationships among organisms?
Select one:
Related organisms always appear identical in embryonic stages.
Adults may have mutations that are not found in embryos.
Evolutionary relationships are more easily observed in more simple organisms.
Features found in embryos may not be found in adults.
Answer:
Related organisms always appear identical in embryonic stages.
Explanation:
Embryos of organisms that have a closer genetic relationship to one another tend to look similar for a longer period of time since they share a more recent common ancestor. Thus, embryology is frequently used as evidence of the theory of evolution and the radiation of species from a common ancestor.
What is Climate Change?
Explain your answer.
What is Climate Change?
Climate change is a change in the usual weather found in a place.
How it helps us:
Studying the climate helps us predict how much rain the next winter might bring, or how far sea levels will rise due to warmer sea temperatures. ... We can also see which regions are most likely to be affected by extreme weather, or which wildlife species are threatened by climate change.
How it works:
As the earth's atmosphere heats up, it collects, retains, and drops more water, changing weather patterns and making wet areas wetter and dry areas drier. Higher temperatures worsen and increase the frequency of many types of disasters, including storms, floods, heat waves, and droughts.
How it affects us:
Human health is vulnerable to climate change. The changing environment is expected to cause more heat stress, an increase in waterborne diseases, poor air quality, and diseases transmitted by insects and rodents. Extreme weather events can compound many of these health threats.

Which of the following will most likely result if all of the primary consumers are removed from this ecosystem?
Answer:
Secondary consumers will lower in numbers and the producers (plants) will be overabundant.
Explanation:
Okay so secondary consumers eat the primary consumers and the primary consumers eat the producers (plants). If there are no primary consumers, there is no one eating the plants which will lead to the producer population growing because there's less stopping them from growing in numbers. The secondary consumers will be in trouble because the secondary consumers don't eat plants. If there are no primary consumers, the secondary consumers won't be able to eat and the numbers of secondary consumers will decrease.

Answer:
100% of the offspring would be black fur, black eyes (16/16)
Explanation:
(Because the info. wasn't included here, I'm assuming black fur and black eyes are dominant, BBEE, to the recessive white fur and red eyes, bbee)
For BBEE x bbee, you'd create a typical dihybrid true-breeding punnett square , where the first top row would be BE , BE, BE , BE , and the vertical/side row would be be, be, be, be.
Cross these alleles as you would typically for any punnett square, and you'd see that all the offpsring would result in BbEe genotypes, which is true of any true-breeding dominant x recessive cross, which always results in the dominant phenotype being 100%.
So...
Black Fur and Black Eyes : 16/16 (100%)
Black Fur and Red Eyes: 0/16
White Fur and Black Eyes: 0/16
White Fur and Red Eyes: 0/16
