When people run quickly, they can sweat profusely. Their muscles undergo movement, and the loss of energy takes place. Based on this description, in which two ways is energy conserved when people run?
Heat energy is released from the body to the surroundings.
Heat energy is taken from the surroundings to the body.
Chemical energy is converted to mechanical energy that’s used for muscle movements.
Radiant energy is converted to mechanical energy that’s used for muscle movements.
Heat energy is converted to mechanical energy that’s used for muscle movements.
Answer: Chemical energy is converted to mechanical energy that’s used for muscle movements.
Heat energy is converted to mechanical energy that’s used for muscle movements.
Explanation:
According to the I law of thermodynamics, energy can neither be created cannot be destroyed but it can only change its form. In the given situation, the energy can only be conserved when it is not lost to the environment. The chemical energy is produced in the body in the form of ATP which is converted into mechanical energy to allow the movement of the muscles during running. So, chemical energy is converted into mechanical energy by this way. The heat energy when directly converted into mechanical energy to induce the movement of muscles the energy will remain conserved and will not lost to the environment.
Answer:
Chemical energy is converted to mechanical energy that’s used for muscle movements.
Heat energy is converted to mechanical energy that’s used for muscle movements.

Explanation:
Both the plant and fungus kingdoms have some common characteristics. ... While both are eukaryotic and don't move, plants are autotrophic - making their own energy - and have cell walls made of cellulose, but fungi are heterotrophic - taking in food for energy - and have cell walls made of chitin.

Use the concept map below to answer the following question.
can you live without a spleen
Answer:
Yes
Explanation:
Although the spleen is an important part of the Immune system, you can survive without it, because the liver can also have the same functions of a spleen. Although the liver can take over these functions it cant prevent all the bacteria that a spleen can prevent.
Due to a extended 5 year drought the seeds became much harder than they were previously which graph would represent how the bird population would change over these years
Answer:
Graph A
Explanation:
With harder seeds, birds will need larger beaks in order to crack the seeds. The birds with smaller beaks won't be able to crack the seeds and will die because they can't eat anything. Graph A is the only one that shows a distinct increase in bird beak size.
In your experiment, you found the following offspring only:Tall green: 626 offspring.Tall yellow: 313 offspring.Short green: 309 offspring.Stay with your original hypothesis/assumption, test it using chi2 test and analyze the result (whether you want to reject the hypothesis and why).(6p)
Complete question:
1. You found a new species of garden pea and have decided to repeat Mendel’s experiments. You have obtained two true-breeding pea plants that are tall (T) with yellow pods (g), and short (t) with green pods (G), respectively. Capital letters indicate dominant traits.
a. What is the genotype and phenotype of the F1 generation? (2p)
b. You allowed self-fertilization in F1 generation and obtained F2 generation. Using Punnett square to obtain the phenotypes, genotypes and their respective ratios. (4p)
2. If you obtained 1248 offspring in the F2 generation in Question 1, calculate how many offspring of each phenotypic class you would expect to have. (4p)
3. When you finish questions 1 and 2, under what assumption/hypothesis did you perform your analysis/calculation? Is there an alternative assumption/hypothesis, which may result in a different conclusion? If yes, what is the alternative assumption/hypothesis and what kind of offspring and in what numbers do you expect to obtain? (4p)

3. If muscle contraction were an athletic game, calcium would be the most valuable player. Describe,
using some depth, the roles calcium is serving both inside the muscle fiber and outside at the NMJ.
Answer:
Explanation:
At the NMJ, calcium is responsible for "unlocking" the ligand gated channels, allowing AcH to be released into the synaptic cleft. When AcH binds and the AP moves down the sarcolemma and into the t-tubule, calcium is then released from the sarcoplasmic reticulum into the sarcoplasm. It then binds to the calcium subunit of troponin, causing a confirmational change in tropomyosin, exposing the active sites on actin. This allows the myosin heads to bind, causing muscle contraction.
List at least 5 importance of gravity in our daily lives
Answer:
- helps us stay on the ground (without gravity we would float and float into space and inevitably die)
- helps us hold things in our hands (even if we let go the objects won't go flying)
- makes it easy for us to do daily things
- lets us understand why things happen and why objects fall to the ground
- suns gravity helps keep the earth the great amount of distance away from the sun so we can get the exact amount of sunshine

Describe passive and active freezing protections that could be set in place for an orchard of apples being grown in New York State and explain why they might be effective.
3 SENTENCES AT THE LEAST
Answer:
A good answer could include planting the trees on the north-facing flank of a hill (passive) and providing overhead irrigation to allow the grower to give plants an ice coating (active). Apples grown in New York face their strongest threat during bloom-time. North-facing plantings partway up a hillside delays bloom-time to later in spring, reducing the odds of the plants experiencing a hard frost. Irrigation allows the grower to take advantage of the severe overall cold that can be associated with a freeze in upstate New York by using the cold to create a protective ice layer that can preserve the blossoms.
Explanation:
this is the example answer. do what you will w it
The passive and active freezing protections can be done by planting facing north hill and providing overhead irrigation respectively.
What is Protection?This is the process of guarding something against damage from an external force.
The passive and active freezing protections are effective as it minimizes the risk of freezes and frosts during spring blooms.

с
ground water.
D

Answer:
Aquifers but since there is no answer choice I say groundwater .
Hope this helps .
Water located in wells underground is ground water. Therefore, the correct option is option C.
Water that is found below the earth's surface in cracks in rocks and the crevices between soil particles is known as groundwater. It is essential for maintaining ecosystems on our planet and supporting human activities. Groundwater is created and made available by precipitation and surface water that seeps into the ground. It gathers in subterranean aquifers, which are enormous water reservoirs contained in permeable rocks or sediments. The thickness and depth of these aquifers vary. Groundwater supply is influenced by elements like rainfall, geology, and human use. Groundwater is an important resource since it is necessary for a variety of purposes. It provides over half of the world's population with their main supply of drinking water.
Therefore, the correct option is option C.

Which animal in a pond food chain would be on the same trophic level as a snake in a grassland ecosystem?
(A) Algae
(B) mosquito larva
(C) fish
(D) racoon
In a pond food chain ecosystem, a fish feed on mosquito, a producer. The fish may get eaten by a racoon, which in turn is consumed by a snake. In a pond, algae is autotroph. So the correct option is D (racoon).
What is trophic level in ecosystem?
Trophic level is defined as the ranking of an organism in the food chain and which differ from a value of 1 for primary producers to 5 for marine humans or mammals.
Racoon is mammal and omnivorous whereas the snake is carnivorous animal. In a pond ecosystems, the biomass pyramid is inverted.
