A muscle moving a load goes through two phases of contraction. Which phase occurs first, and what happens inside the muscle during this phase
The phase that occurs first when a muscle carries load is called the contraction phase.
Phases of muscle contractionWhen lifting up a load, the muscle passes through some phases of contraction such as:
contraction phase andrelaxation phaseThe series of events that occurs in the contraction phase include the following:
Depolarisation and calcium ion release.Actin and myosin cross-bridge formation.Sliding mechanism of actin and myosin filaments.Sarcomere shortening (muscle contraction)Therefore the phase that occurs first when a muscle carries load is called the contraction phase.

Which of the following BEST explains why Earth is tectonically active?
Answer:C Earth's solid surface layer sits on a moving, semiliquid layer.
Explanation:
Earth is highly tectonically active because the solid layer of the earth sits on a moving, semi-liquid layer.
The earth's crust is broken into slabs. Together with part of the upper mantle, they form a layer called the lithosphere. These solid lithospheric bodies are called tectonic plates.
Why must DNA replication have to occur before a cell can divide by mitosis?
A. to cause one of the cells produced to have double the number of chromosomes as the parent cell
B. to allow crossing over to occur in each of the cells produced
C. to maintain the same number of chromosomes in the daughter cells as in the parent cell
D. to cause all of the cells produced to have half the number of chromosomes as the parent cell
Answer:
C
Explanation:
DNA replicates because the second set of DNA will move into the new cell during telophase. double-check in your text but C is the most accurate answer given. A doesn't happen unless there's a breakdown in cell division, and D is for meiosis when a diploid cell divides into a haploid cell. B could be correct but it's not entirely accurate.

Suppose you are a chemist lost in the desert and desperately in need of water. If you had a chemistry set available, which type of reaction could you use to make water?
A) dehydration
B) exothermic
C) hydrolysis
D) redox
Answer: Hydrolysis tell me how I'm wrong
Explanation: Hydrolysis is any chemical reaction in which a molecule of water breaks one or more chemical bonds. The term is used broadly for substitution, elimination, and solvation reactions in which water is the nucleophile
Dehydration is the absence of a sufficient amount of water in your body. The best way to beat dehydration is to drink before you get thirsty. If you're thirsty, you're already mildly dehydrated, and that can cause symptoms like headache, fatigue, dizziness, and more.
Exothermic: ----> (of a reaction or process) accompanied by the release of heat.
(of a compound) formed from its constituent elements with a net release of heat.
Redox: ---> a process in which one substance or molecule is reduced and another oxidized; oxidation and reduction are considered together as complimentary processes.
"redox reactions involve electron transfer"

What kind of reaction is responsible for the liberation of carbon dioxide in red blood cells
Answer:
Bifurcate Buffer system
Bifurcate Buffer system is a reaction defined as a cell mechanism in which liberates approximately 85% of the total carbon dioxide. This is the system in which the actual diffusion of the cells happen. Carbon Anhydrase present in the blood is responsible for the conversion of into Carbonic Acid.
can i get some help with this pls
Answer:
The answer would be 8.
Explanation:
To find volume you need to do Length x Width x Height
L x W x H
That would be:
8 x 1/2 x 2
8 x 1/2 = 4
4 x 2 = 8
So the answer is 8.

three dangers to mangroves
Answer:
Coastal Development. Coastal development may be the primary threat to mangroves. Not only are the forests lost when a coast is developed, but a man-made structure almost always replaces them.
Aquaculture, Agriculture & Salt Production. The close proximity of mangroves to the ocean makes them ideal locations for shrimp farming and other kinds of mariculture.
Deforestation. Most destructive uses of mangrove forests require their removal. The motivations behind deforestation include direct use of the mangrove wood and leaf products, or use of the wetland habitat.

What information can you collect about the process that form copper across the world
Answer:
The high temperatures of volcanic magma creates hydrothermal veins, allowing some of the heat to escape near the upper layers of the Earth's crust. This is why copper is often found in the sedimentary layer, where sand and mud are compressed until they form a layer of sedimentary rock on the surface of the earth.

OKEASE HELP WILL GIVE BRAINLIEST
The correct answer is: A. the same traits
Homologous chromosomes come in pair: one inherited from the mother and one inherited from the father. They have the same genes in the same loci, meaning that those genes code for the same traits. But, variants of those genes-alleles can be different e.g. one recessive one dominant). During the meiosis (cell division of gametes) homologous chromosomes align correctly with each other before separation.

Write a main idea paragraph about cells in general (5 sentences) I'll mark brainliest !
Biologists recognize five levels of cell organization. The lowest and simplest is the cellular level. Organisms here are either unicellular organisms, like protozoa, or colonial organisms. Colonial organisms are composed of single-celled individuals that stay together to sustain the life of the whole colony. Next on the scale of complexity is the level occupied by tissue. A tissue is a group of similar cells that perform a similar activity. Tissues that are organized around a common function together make up an organ, the third level of complexity. The fourth level of organization is the system, formed by a group of organs that together perform a specific bodily process. The fifth and highest level is the organism level, in which body systems work together in a structure capable of independent life.
