Read the following summary, which describes blood flow and heart output in space. Then, answer the question.
The heart doesn't have to do as much work to pump blood when in orbit. After only one day beyond Earth's gravity, astronauts have a lower blood volume. They can lose as much as 20 percent of their blood volume while on a space mission. Since the body has less blood to push around and the heart is pushing more blood with each beat, an astronaut's heart rate also slows down to compensate.
What process is being described?
Breathing
Excretion
Homeostasis
Respiration
Explanation:
respiration because it's about blood circulation

Which of the following best describes evidence from comparative embryology regarding embryos of different species that supports the theory of evolution?
They carry out similar metabolic processes.
They develop in similar environments.
They have the same genome.
They share similar development patterns.
Answer: D.
Explanation: Thus, Comparative Embryology provides strong support for the hypothesis that Darwin put forth to explain the apparent similarities and differences he saw among different species, i.e. that these species are the result of an evolutionary process involving selection (now known to be gene based) for structural and In the mid-1800s, Charles Darwin and Alfred Wallace independently concluded that inherited variations in traits, such as a bird's beak shape, may provide better odds of survival in a given niche. Organisms without the advantageous variation are less likely to survive and pass on their genes.
Answer:
they share similar development patterns

Structure of plant cell
Answer:
A cell wall, a broad central vacuole, and plastids such as chloroplasts are all present in plant cells. The cell wall is a dense layer that covers the cell and provides structural support and protection. It is located outside the cell membrane. The turgor pressure against the cell wall is maintained by the central vacuole.

How are the jobs of bones and muscles different?
Answer:
Bones provide structure and form for your body and protect and support vital organs and work with muscles to help the body move. They gain strength and stability,while the primary job of muscle is to move the bones of the skeleton, but muscles also enable the heart to beat and constitute the walls of other important hollow organs
Explanation:
Hope this helped!!!!
Answer:
Bones are like the wireframe and structure of a building. Without it, it cannot stand. Muscles, on the other hand, help move body parts by pulling on your bones and contracting and relaxing. They are like the walls, flooring, and everything else (disregarding furniture) and without that, the building is bare and you have nothing to walk on...

If both the biceps and triceps muscle contract at the same time, what happens?
Answer:
when one muscle is contracted, the other muscle from the pair is always elongated. for example, the biceps and tricep muscles work together to allow you to bend and straighten your elbow. when you want to bend your elbow, your bicep muscle contracts. and at the same time tricep muscles relaxes.

Explanation:
The above are the parts of a musculoskeletal system.
The musculoskeletal system is actually known as an organ system which is made up of specialized tissues of the bones and skeletal muscles. The system consists of the bones of the body, muscles, ligaments, cartilage, tendons, joints and other connective tissues. These all work together in the musculoskeletal system to provide support for the body. They enable motion of the body and provide protection to vital organs in the body.

As the territory of Africanized bees continues to expand, what is the most likely outcome?
Answer:
Competition among nectar- and pollen-feeding invertebrate pollinators and resource partitioning are affected by introduced Africanized Honey Bees. When Africanized Honey Bees compete with other species of honey bees for flowers, the Africanized bees may displace the other bees from the food sources.

11. If the decomposers were removed from an ecosystem, what would
most likely occur?
Energy from the sun would not be absorbed by plants
Carnivores would have no source of energy
Essential elements would not be available to plants
Herbivores would lose their source of energy and nutrients
Answer:
If decomposers are removed from ecosystem,there would be no organic nutrients and all the dead plants would destroy the animals habitat. The ecosystem will be fill by plants and animal wastes as there will be no decomposition of waste material.
If the decomposers were removed from an ecosystem then essential elements would not be available to plants. The correct option is C.
What are decomposers?Decomposers eat dead things like leaf litter and wood, as well as animal carcasses and feces.
As Earth's cleanup crew, they provide a valuable service. Dead leaves, insects, and animals would pile up everywhere if decomposers did not exist.
They play a critical role in decomposing complex compounds (dead organisms) into simple components.
Scavengers and decomposers break down dead plants and animals. They also decompose other waste of organism.
Decomposers are critical components of any ecosystem. Plants would not receive essential nutrients if they were not present in the ecosystem, and dead matter and waste would accumulate.
Thus, the correct option is C.

In the graph, “ppm” stands for parts per million. A concentration of one ppm is a ratio of one part to one million parts. Concentrations can also be expressed as a percentage. Why do you believe scientists choose ppm over percentage in some cases?
Answer: very small amounts are easier to express as ppm.
Explanation: 1 ppm = 0.0001 %
Answer:
Concentrations like the ones shown in the graph are relatively small. Writing them as percentages would require decimal points and many leading zeros. Therefore, scientists choose ppm over percentages to show CO2 concentrations.

based on the reading above describe two diff between mysteceti and odonticeti whales one diff should be in anatomy and the other in feeding behavior. plz help me guys give a short answer
Answer:
both are different in feeding behaviour and blowholes.
Explanation:
The main difference between Mysteceti and odonticeti whales is the presence of feeding behaviour. Mysteceti whales also known as baleen whales which have baleen plates that capture prey from sea water while on the other hand, odonticeti whales have teeth which helps these whales to hunt aquatic animals. Baleen whales have baleen plates, or sheets, which sieve prey or food from seawater whereas toothed whales have teeth which helps them to actively hunt fish, squid and other sea creatures. The number of blowholes also different in both whales, Odontoceti whale has only 1 blowhole, but the Mysticeti has two blowholes in its body.

Puzzle 8
5 Hibiscus flowers
begin the clue.
Now do you know
what to do?
Answer:
The first answer is 1
The second answer is ≠
Explanation:
From the attached image, we are giving a clue that there are 5 Hibiscus flowers.
So, each symbol of the Hibiscus flower is 5.
1st row: Hibiscus + Tree = 14
⇒ 5 + Tree = 14
∴ Tree = 14 - 5 = 9
This means that the tree represents 9
2nd row: Sunflower + Hibiscus = 13
⇒ Sunflower + 5 = 13
∴ Sunflower = 13- 5 = 8. This means that the sunflower represents 8.
3rd row: Tree - sunflower = 9-8 = 1
4th row: Sunflower + tree = 9+8 = 13
Last row: Hibiscus(5) × Sunflower(8) ≠ Tree (9)
