A burning coal
B using ethanol in cars
C installing solar panels on a home
D generating electricity in a hydroelectric power plant

Group of answer choices

Answers

Answer:

D. generating electricity in a hydroelectric power plant.

Explanation:

Renewable energy is also known as clean energy and it can be defined as a type of energy that are generated through natural sources or technology-based processes that are replenished constantly. Some examples of these natural sources are water (hydropower), wind (wind energy), sun (solar power), geothermal, biomass, waves etc.

Basically, a renewable energy source is sustainable and as such can not be exhausted.

Generating electricity in a hydroelectric power plant best describes a method of obtaining energy which may cause changes in water temperature and harm to fish populations. This is due to the operation of powerful electric steam turbines operating at high voltage.

D. Explain the relationship between the pulse recorded in the finger and heart muscle contraction ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ E. Which components of the cardiac cycle (atrial systole and diastole, ventricular systole and diastole) are discernible in the pulse tracing? ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________

Answers

Answer:

D. Heart contraction and pulse are connected with one another.

E. Atrial diastole and ventricle diastole.

Explanation:

Heart construction and pulse of an individual are connected as one can hear the pulse every time contraction of the heart is completed. Pulse can be understood by this that it represents the number of the contractions is completed by heart each time.

In the pulse tracing, there are two parts of the heart that are discernible which represents the contraction of the heart that are Atrial diastole and ventricle diastole.

The relationship between the pulse recorded in the finger and heart muscle contraction is that both are connected to each other. But, the analysis and processes are different from one another.

What is Muscle Contraction?

A process leading to shortening and/or development of tension in muscle tissues that means the thin filaments slide over the thick filaments and tension is generated between one another is called Muscle contraction.

The pulse recorded in the finger is a signal for flowing the blood throughout the body, while the process of heart muscle contraction signals for electrical conductivity. Both the functions are connected with each other and acquired by cardiac activities.

The components of the cardiac cycle that are discernible in the pulse tracing are Ventricular systole (contraction) and ventricular diastole (relaxation).

Therefore, both the pulse recorded in the finger and heart muscle contraction interconnected with one another and acquired by cardiac activity.

The test statistic for this hypothesis test is - 3.68.

Explanation:

A test statistic is a random variable that is calculated from sample data and used in a hypothesis test. You can use test statistics to determine whether to reject the null hypothesis. The test statistic compares your data with what is expected under the null hypothesis.

Sample proportion = 38/50

Darwin and Wallace both observed greater species richness in the tropics than in Europe, but neither of them had a good explanation for why. One of the best-supported modern-day hypotheses to explain this pattern is that mutation rates are higher in the tropics than in temperate latitudes. Why would higher mutation rates lead to greater species richness

Answers

Answer:

Mutation shows the species energy relationships, tropics are more rich with energy as compared to the temperate europe.

Explanation:

The rate of species evolution is defined by the type of environment or the natural surroundings it lives in. Mutations Can affect organisms by making changes in their physical characteristics. Such can impact their DNA code and may even lead to death in many. The richness of species in the tropics is due to the more warmer and humid climates. They are suited to the development and germination of certain bacterias and have certain climatic phenomena.

The cardiovascular system is composed of two circulatory paths: pulmonary circulation and systemic circulation.
Pulmonary circulation transports deoxygenated blood from the right side of the heart to the



A. left side of the heart where it is pumped to the lungs for oxygenation

B. lungs where blood picks up oxygen and returns to the left side of the heart

C. lungs where blood picks up oxygen and returns to the right side of the heart

D. lungs where the blood picks up oxygen and transports it to the tissues of the body

Answers

Answer:

B. lungs where blood picks up oxygen and returns to the left side of the heart.

Explanation:

In Human anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.

Generally, the cardiac cycle occurs in two (2) stages;

1. Diastole : in this stage, the ventricles is relaxed and would be filled with blood.

2. Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.

The cardiovascular system comprises of two circulatory paths:

I. Pulmonary circulation.

II. Systemic circulation.

Pulmonary circulation transports deoxygenated blood from the right side of the heart to the lungs where blood picks up oxygen and returns to the left side of the heart.

The pulmonary circulation loop is mainly supported (powered) by the right atrium and right ventricle.

Additionally, the right atrioventricular valve (AV) also referred to as the tricuspid valve is located on the right dorsal side of the human heart. The right atrioventricular valve (AV) comprises of three (3) leaflets (flaps) which opens and closes in order to allow for the flow of blood from the right atrium of the human heart to the right ventricle. Also, the right atrioventricular valve is saddled with the responsibility of preventing blood from flowing backward in the mammalian heart.

Explain how meiosis results in UNIQUE cells.

Answers

Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. This produces a unique combination of genes in the resulting zygote. Recombination or crossing over occurs during prophase I. The result is 4 haploid daughter cells known as gametes

Meiosis is a reduction division in which the number of chromosomes in the parent cells is halved to the daughter cells.

Meiosis is the process such as:

Meiosis occurs in the reproductive cells of humans.

Meiosis transmits genetic information from parent to offspring.

Meiosis is the characteristic feature of sexual reproduction.

The male and female gamete fuse to give rise to a newly formed combination of the daughter cells.

Meiosis results in the recombination of male and female gametes, which results in the independent assortment of the genes.

Thus, meiosis always results in new variations and creates genetic diversity.

Most of the oxygen in the atmosphere is made by algae. Where do most of the algae live?
coastal ocean
deep ocean
ponds
lakes

Answers

Coastal Ocean!

Explanation: It’s important to remember that although the ocean produces at least 50 percent of the oxygen on Earth, roughly the same amount is consumed by marine life. Like animals on land, marine animals use oxygen to breathe, and both plants and animals use oxygen for cellular respiration. Oxygen is also consumed when dead plants and animals decay in the ocean.

This is particularly problematic when algal blooms die and the decomposition process uses oxygen faster than it can be replenished. This can create areas of extremely low oxygen concentrations, or hypoxia. These areas are often called dead zones, because the oxygen levels are too low to support most marine life.

NOAA’s National Centers for Coastal Ocean Science conducts extensive research and forecasting on algal blooms and hypoxia to lessen the harm done to the ocean ecosystem and human environment.

Most of the oxygen in the atmosphere is made by algae, with coastal oceans housing the majority of algae. Hence the correct option is A.

What is Algae?

Algae is defined as a member of a group of primarily aquatic photosynthetic organisms of the Protista kingdom. Algae is described as floating green matter on the surface of a pond, lake, river, still water, moist soil, stones that grow on wet surfaces. Therefore, they can synthesize their own food. They are found in water or in very moist places.

Algae play many important and beneficial roles in freshwater environments producing oxygen and consuming carbon dioxide that act as the base of the aquatic food chain, removing nutrients and pollutants from the water and stabilize sediments. Most of the oxygen in the atmosphere is made by algae, with coastal oceans housing the majority of algae.

Analyzing the following tree, prove the relationship between ray-finned fish and crocodiles using the characteristics given below. Include at least three (3) characteristics that the organisms DO NOT have in common and one characteristic that they DO have in common. Your paragraph should be at least four (4) sentences. Remember to answer in COMPLETE sentences and use proper grammar.

Answers

Answer:

The Ray- Finned Fish has a bony skeleton just like crocodiles. Crocodiles evolved more and adapted to their environment. Along the way Crocodiles grew to have four limbs, were born from an amniotic egg, and then their eggs also have shells, unlike the Ray-finned fish. Therefore the three characteristics they do NOT have in common are: Four Limbs, Amniotic Egg, and Eggs with Shells. The one trait they do have in common is Bony Skeletons. They also both have vertebrae.

Scientists recently published a paper about an endangered population of Scarlet Bass (species A) in Lake Erie. The authors also published its entire mitochondrial DNA sequence on Genbank, an online system where scientists submit genomic data. Another group of scientists later published an article using molecular data to estimate gene flow among populations of the very abundant Grey Bass species (species B) in Lake Erie, and published mitochondrial data on Genbank as well. After you read the papers you realize that the ranges for species A and a few isolated populations of species B overlap; you look at the sequence data published online from both studies, and you realize they are very similar and differ only by a few nucleotide differences. 8. Do you think these are closely related species, or variants of the same species

Answers

Answer:

They are variants

Explanation:  

The biological concept of species states that members of the same species can reproduce they have a genetic reservoir in common: many genetic variants.

Genetic variability is the measure of a species organism´s tendency to differentiate. In genetic variability, individuals of the same species are not identical. They are recognizable as members of the same species, but they differ in shape, function, and behavior. There exist variations among individuals of the same species.

Genetic variability originates from mutations, recombinations, and karyotype alterations. It allows or makes possible evolution.

Groups A and B can be considered variations of the same species. They not only overlap but also share most of the genetic sequences with only a few nucleotide differences.

These variations might be the previous step for sympatric speciation.
