Answer: 28%
Explanation:
Use Chargaff's rules which states that 100% is total of all 4 bases and Adenine and Thymine need to have 1:1 ratio and Cytosine and Guanine need to have 1:1 ratio
21% Adenine and 21% Thymine
21% + 21% = 42 100 - 42 = 56 56 / 2 = 28
28% Cytosine and 28% Guanine
Scientists believe that the polar bear in Alaska and the brown bear in Russia evolved from a common ancestor which would be responsible for this evolutionary change
Answer: don’t know really how to explain it but it’s geographic isolation
The process which is responsible for the evolutionary change among polar bears in Alaska and the brown bear in Russia is geographical isolation.
What do you mean by Evolutionary change?Evolutionary change may be defined as the heritable change which is seen in populations and species over a long period of time, due to several mechanisms such as natural selection, random genetic drift, erotic selection, and mutation.
The mechanism of geographical isolation is considered one of the important factors in causing speciation.
This happens when the individuals of the species may be isolated due to any physical means such as mountains, rivers, etc for a long period of time.
Therefore, the process which is responsible for the evolutionary change among polar bears in Alaska and the brown bear in Russia is geographical isolation.

describe how lactobacillus is important in human intestine???
Answer:
This genus of microbes breaks down dietary fibers and phytonutrients (like polyphenols) which have beneficial effects for your health. What's more, Lactobacillus even helps to feed other bacteria in your gut, such as the ones that produce butyrate (which the cells in your gut lining need for energy).

Explanation:
Gametes (SEX CELLS) have ... A. half the number of chromosomes found in the body cells B. twice the number of chromosomes found in body cells C. two sets of chromosomes
Answer:
A. Half the number of chromosomes found in the body body cells
Explanation:
Somatic (body cells) have 2 sets of chromosomes, while gametes have 1 set of chromosomes. Sperm has one set, and an egg has one set allowing both to fuse to create a new organism.
Answer:
[tex]\boxed {\boxed {\sf A. \ Half \ the \ number \ of \ chromosomes \ found \ in \ the \ body \ cells}}[/tex]
Explanation:
Gametes are sex cells, such as the egg and sperm. They are used in sexual reproduction to produce offspring.
The sex cells are produced during meiosis. The DNA or genetic material is replicated, then the cells divide twice. After this, four haploid cells are produced with half of the genetic material. For example, human body cells have 46 chromosomes but sex cells have 23 chromosomes.
They contain half the genetic material for an important reason. During fertilization, an egg and a sperm fuse. Each one contributes half of the genetic material from the mother or father to create one complete set for the offspring.
Gametes have half the number of chromosomes in body cells and choice A is correct.

Answer:
Using your gloved hand to apply pressure on the wound to control bleeding. b. Direct pressureBleeding that can be seen coming from a wound. a. External bleeding The escape of blood from an artery, vein, or capillary inside the body. d. Internal bleeding A tight band placed around an arm or leg to constrict blood vessels in order to stop blood flow to a wound. g. TourniquetBlood vessels that carry blood from all parts of the body to the heart. f. Veins Vessels that transport blood to the capillaries for distribution to the cells. e. ArteriesA bandage applied snugly to maintain pressure on the wound to control bleeding. c. Pressure bandageExplanation:
Direct pressure is a technique used to stop the bleeding on the wound. The person should place both hands over the wound and press firmly till doctors arrive. With this first aid technique, we prevent excessive blood loss, which can cause worse problems in the future.
There are two types of bleeding, external and internal. In the first one, the skin opens, and blood comes out to the exterior. In the second one, the skin is not open, so the blood does not come out to the exterior, but blood goes to tissues around the broken vessel due to an internal injury.
A tourniquet is a first-aid technique use to stop blood flow and prevent that the injured person bleeds out till death. A band, a piece of shirt, or a belt should go around the limb and tie it hard to stop the blood flow and allow the patient to arrive at the hospital. It is a technique usually use when there is a wound that affects the main vessels.
There are different types of vessels. They change in size and structure. Veins are the vessels that carry blood back to the heart, where it will go to the pulmonary circuit to be oxygenated. Arteries will take the oxygenated blood from the heart to the rest of the body. The arteries branch into small vessels called arterioles, and the arteries branch into capillaries which will give oxygen to the cells.
A pressure bandage controls bleeding and prevents the injury from being contaminated. The pressure bandage does not restrict blood flow as a tourniquet.

Explique de qué manera la deriva continental ha influido en la distribución de especies vegetales y animales en el mundo.
Answer:
la deriva continental ha notablemente influido en la distribución actual de las especies. Este fenómeno se puede observar en grupos de organismos similares que se encuentran en diferentes continentes, lo cual concuerda con la idea de que la separación entre dichos continentes se produjo más tardíamente en el tiempo
Explanation:
La teoría de la deriva continental plantea que durante el final del Paleozoico y el principio del Mesozoico (hace aproximadamente hace 225 millones de años) las masas continentales actuales se encontraban unidas formando una gran masa de tierra o supercontinente conocido como 'Pangea'. Esta teoría se basa en evidencia de diversa fuentes incluyendo pruebas geográficas (coincidencias en las costas de algunos continentes), paleontológicas (mismos fósiles en diferentes continentes), geológicas y tectónicas (por ej., la presencia de cadenas montañosas que se separaron hace millones de años), y paleoclimáticas (evidencia de climas similares durante el pasado en continentes diferentes). La deriva contiental afectó la distribución actual de especies de plantas y animales. Por ejemplo, la fauna en Europa es semejante a la observada en Norteamérica porque estos continentes se separaron más tardíamente en el tiempo que otros contientes/masas de tierra del hemisferio sur, y dichas semejanzas se encuentran reflejadas en organismos evolutivamente más relacionados (menor tiempo de divergencia evolutiva).
Hypothesize what could happen if finches from one island of the
Galapagos were relocated to another island.

Population Growth
Project: Analyzing Factors That Affect Carrying Capacity and Biodiversity
In this assignment, you will use simulations to analyze how climate, resources, and habitat size affect
carrying capacity. You will then look at another simulation to analyze the effects of certain factors that
affect biodiversity and populations. Finally, you will write and revise a conclusion on how human activity
affects biodiversity.
Background Information
Population growth is the change in size of a group of organisms of the same species over time. It is
affected by four factors: birth rate, death rate, immigration, and emigration.
Carrying capacity is the maximum total population that an area can support. Carrying capacity limits
population growth and is affected by competition for food, water, shelter, or mates, and threat of
predators, disease, and parasites. Carrying capacity may be affected by one or a combination of these
factors.
Biodiversity is the total variety of organisms that live in the biosphere. Biodiversity is affected by the loss
of habitat, introduction of invasive species, pollution, and/or human activities.
Answer:
Question 1: How does increasing the size of the habitat affect carrying capacity? Explain your answer. Recall the scenarios: 0–15 years, Little land; 15–30 years, Moderate land; 30–45 years, Ample land.
Population numbers self-regulate to some extent since mortality rise when a population exceeds its carrying capacity. Carrying capacity is affected by disease, competition, predator-prey interactions, resource usage, and the number of populations in an ecosystem.
Explanation:
Question 2: How and why did changes in the environmental conditions affect carrying capacity in this scenario? Recall the scenarios: 0–15 years, Harsh winter; 15–30 years, Harsh winter and Cold spring; 30–45 years, Harsh winter, Cold spring, and Hot summer.
The carrying capacity of an environment is also affected by conditions within or adjacent to it. If the environment is adjacent to a human population, for example, this may have an impact on its carrying capacity. Pollution can also have an impact on the carrying capacity of an environment.
Question 3: If there were no other changes in the habitat, would the value under “Larger Than Ample” be correct? Why or why not
Climate change isn't only about global warming. While it is true that temperatures would rise during the summer months, it is also feasible that the winter months would be even colder. As a result of this effect, the winters will be exceptionally cold from year 0 to 15.
Question 4: Suppose there were changes in the habitat that caused this actual value. What might a combination of those changes be
Assume that the climate in a habitat shifts. The amount of precipitation reduces by 20% over time. It will have an impact on the habitat because species that have adapted to drier climates will supplant those that are less suited to the new climate. This best circumstance explains the cause for adaptation, and those that adapted rapidly will replace those who found it difficult to adapt, resulting in the extinction of species as those who can thrive will be able to cope with the rapid shift in the environment. The most fittest survive in the new environment, according to Charle's Darwin thesis.
Question 5: How would you describe the effect of a 1°C increase of temperature on the biodiversity of the habitat in terms of number of populations and number of individuals in the populations? Use evidence from your graph and table to support your answer
The graph and table in the supplied question were not provided, nor could they be found anywhere, hence the question was answered based on prior knowledge. Earth's species can adapt to their surroundings, however adaptation in organisms can take thousands to tens of thousands of years. However, for the last 200 years, a consistent rise in temperature has been recorded.
The thermal limits of species residing in the tropics, equator, and poles have already been altered. If the global average temperature rises by one degree Celsius, the number of people on the globe will drop. The population of a species will decline as the number of individuals decreases.
