What two body systems will work together to provide cells with energy?
A. Excretory and Digestive, because the nutrients from the digested food will be sent to the excretory to be delivered out as waste products.
B. Digestive and Muscular, because the nutrients from the digested food will be used immediately by the muscles for energy.
C. Respiratory and Excretory, because the oxygen will be transported to the cells so that wastes can be delivered out as a waste production.
D. Digestive and Cardiovascular, because the food will be broken down and nutrients will be sent in the bloodstream to the cells for use.
Answer:
Answer:
The correct answer for the first question would be B) the respiratory and circulatory systems.
Respiratory system is a set of organs which help in exchange of gases in the body. They bring oxygen from outside into the body and release carbon dioxide from inside the body to outside world. The exchange of the gases takes place at alveolar site (or gills in aquatic animals).
The circulatory system then carries this oxygen (mixed in blood) from gas exchange site to all the cells of the body. In addition, it also brings carbon dioxide (waste product of cellular respiration) from all the cells to the gas exchange site (respiratory system).
The correct answer of the second question would be C)the digestive and circulatory systems.
Digestive system helps in breaking down of macro-molecules (such as starch, polypeptide, fats) into smaller units (such as glucose, fructose, amino acids) as well as absorption of the same.
Nutrients from the absorptive site (usually small intestine) are then transported to the entire body with the help of blood through capillaries and arteries that is, circulatory system.
Explanation:
Body systems that will work together to provide cells with energy are:-Digestive and Cardiovascular, because the food will be broken down and nutrients will be sent in the bloodstream to the cells for use.
Digestive system will breakdown complex macromolecules into micro molecules which are then transferred into blood.Blood or Cardiovascular system will carry these micro nutrients to different parts of the body Describe digestive system?It is system that include organs that take in food and liquids and break them down into substances that the body can use for energy.
Describe cardio vascular systemThe circulatory system or cardiovascular system pumps blood from the heart to the lung to get oxygen. The heart then sends the oxygenated blood through arteries to the rest of the body. Veins carry deoxygenated blood from various parts of the body to lungs.To know more about body systems here

A section of one DNA strand has the sequence ACC GAG GTT. What is the sequence of the strand it binds to?
Answer:
UGGCUCCAA
Explanation:
Basically when you transcribe DNA into mRNA, you find the complementing base pair, for example if G is written in the DNA, the mRNA would show C, and if an A was in the DNA, a U would be shown. It is NOT THYMINE in RNA!! This changes to Uracil in RNA, and that is VERY important. The reason why it is flipped is because of the tRNA. So 3 mRNA nucleotides make a codon, and the tRNA are also in sets of 3, but are called anticodons. The tRNA is complementary to the mRNA strand, AKA the same as the DNA strand except with Uracil instead of Thymine. This is because Thymine breaks down in the presence of Oxygen and so is replaced by Uracil.

from a particular location on earth, why can we see many more total eclipses of the moon that the total eclipses of the sun?
Answer:
Hiii! I'm here to help!
Explanation:
The Moon is always in the same place in our sky while the Sun moves around the sky. The Moon is much bigger in the sky than the Sun. The line-up of the Earth Moon and Sun needed for a lunar eclipse happens many many times more often than what is needed for a solar eclipse. A total lunar eclipse is visible over a much larger part of the Earth's surface than a total solar eclipse.

Answer:
1. It's difficult to find out if someone is blood doping because the body has red blood cells. First the doctors get blood samples. Because the body constantly produces new blood, the blood that was stored shows that it is old with the blood samples it shows that there are some new and some old blood cells, which is how you can tell if they are doping.
2. Hemoglobin is a protein that is produced by the body that carries oxygen in the red blood cells the more red blood cells the more hemoglobin you have. Ex; If the athletes have a high level of hemoglobin on the day of the race than it had been days or weeks before, to shows that the athlete was blood doping.
3. It can help the body produce more blood cells to carry more oxygen (get more energy) and the body can get used to that kind of high altitudes and climates. Which leads to you getting even more energy at lower altitude levels.

onsider a scenario where a native plant population is growing at it's carrying capacity in a community. The seed of an invasive species is brought in by a squirrel, which then germinates, grows and reproduces resulting in the establishment a population of this invasive plant species. The invasive species has very similar niche as the native plant species. How do you predict the invasive plant population to be affected by the presence of this native species
The given question is incomplete, the complete question is:
Consider a scenario where a native plant population is growing at it's carrying capacity in a community. The seed of an invasive species is brought in by a squirrel, which then germinates, grows and reproduces resulting in the establishment a population of this invasive plant species. The invasive species has very similar niche as the native plant species. How do you predict the native plant population to be affected by the presence of this invasive species?
The invasive species fitness will be limited by the native plant species
The native plant carrying capacity will go down, relative to that prior to the invasive species arrival
There will be no change to the native plant population
The invasive species will grow unchecked and exponentially
No listed answer is correct
Answer:
The correct statement is the fourth one, that is, the invasive species will grow exponentially and unchecked.
Explanation:
The fitness of the invasive species will not get restricted by the native species. Though the opposite takes place as the original niche of the local species does not possess the natural predator for the invasive species. Therefore, invasive species emerge fitter and reproduce exponentially without population control.
The carrying capacity of the native species will not go down before the arrival of the invasive species, however, will go down post its arrival.
As the invasive species has no natural predators, one can witness a substantial reduction in the population of the local plant population. The invasive species will utilize the niche of the local plant, therefore, resulting in the reduction of the native species population, as they have share habitat, food resources, and other natural resources.
It is correct that the invasive species will grow without any control. An outbreak of invasive species generally takes place due to the absence of its natural predators in the ecosystem at the time of its introduction. Hence, the correct statement is the fourth one.
Invasive species establish in a new area, overgrow, and negatively interact with native species. The correct option is 4). The invasive species will grow unchecked and exponentially
-----------------------------------
Let us firts reviw some framework.
When talking about dispersion, we refer to the change in a species' range or distribution area.
When species move and establish in a new area, out of their original distribution range, they might be considered exotic or invasive, according to their
• reproductive rate,
• population growth, and
• interaction with native species.
The introduction of invasive species has ecological, economic, socio-cultural consequences.
Once an invasive species has been established, it overgrows.
In the new areas, these species have less environmental pressure and better conditions than in their origin area -fewer predators, more resources, better nitches-.
These factors favor their establishment because they are adapted to surviving under harder conditions.
They interact with native species by competing for resources such -water, place, radiation, exposure, shelter, food, etcetera-.
They can also become significant predators of native species, consuming a wide diversity of prey items, and in many cases, there are no native species that may prey on them.
They provoke significant damages in the structure of native ecosystems, causing severe damage in endemic species.
They produce ecological imbalances in the trophic chains and the dynamics of communities. Invasive species are uncontrollable.
As they expand, they can also affect human in an economic manner and has socio-cultural effects. Many invasive species might cause crops loss by eating cultures. They attack farm animals. They affect buildings and other structures or ships by eating wood. They might even attack humans and cause health problems.
According to this information, we can answer the question.
We need to predict how NATIVE species are affected by INVASIVE species.
The options are,
1) The invasive species fitness will be limited by the native plant species
When talking about invasive species, this is not an option. Invasive species always affect the fitness of native species. So this option is not correct.
2) The native plant carrying capacity will go down, relative to that prior to the invasive species arrival
The carrying capacity will still be the same. But resources availability will decrease faster because both species have the same requirements. They compete for the same resources. This option is not correct.
3) There will be no change to the native plant population
The will occur changes for the native population for sure. It will be affected by the presence of invasive species. So this option is not correct.
4) The invasive species will grow unchecked and exponentially
Invasive species population will express an uncontrol exponential growth during its establishment phase.
This plant species find the perfect conditions to reproduce and increase its population size.
It finds available space, no predators, water and nutrients availability, proper light exposure, among others.
They can successfully compete with native species, displacing them and getting more space.
THIS IS THE CORRECT OPTION
5) No listed answer is correct
Not correct

How was the rotation rate of Jupiter's core determined?
-by observing the Great Red Spot
-by watching lo move across the disk of Jupiter
-by radio observations of Jupiter's rapidly spinning magnetosphere
-by measuring the oblateness of Jupiter's disk
Answer:
C. by radio observations of Jupiter's rapidly spinning magnetosphere
Explanation:
Jupiter refers to one of the planetary bodies in the solar system. It is considered to be the largest (twice as large or big as every other combined) planetary body and the fifth (5th) from the Sun.
Jupiter is a planet that rotates rapidly and as a result it is referred to as being noticeably oblate. It has the fastest rotation rate among the planets of the solar system because it completes a rotation about an axis in 9.9 hours.
The rotation rate of Jupiter's core was determined by radio observations of Jupiter's rapidly spinning magnetosphere.
