Uses carbon dioxide from the environmentUses the electrons (carried by NADPH) and ATP from the light dependent reaction as source of energyBuilds CH1,0 molecules (aka, glucose/carbohydrates/sugars)Explanation
The light-dependent reactions of photosynthesis require energy from the sun to split a molecule of water into hydrogen and oxygen. The oxygen is released and the hydrogen ions are used as energy for the next steps, as is ATP.
In the light independent reactions, sugar is made from carbon dioxide using the energy from the light-dependent steps
Humans are able to move their shoulder 360 degrees. What morphological features aid in this degree of motion (i.e. which bones)? Examine the bat wing below. Is there the same degree of motion? Explain why or why not.
Answer:
This question is incomplete because of the absence of bat diagram discussed in the question
Explanation:
Humans body contains several joints that allows from movement of bones at some junctions called the "joints". Joints are points where two bones meet. Examples of the human joints include the ball and socket joints, hinge joint, pivot joint, gliding joint, saddle joint. The type of joint in the human shoulder that allows for 360 degrees rotation is the ball and socket joint. It involves a bone that has a round head like that of a "ball" which can fit into an open cup-like shape called the "socket", hence the reason for the name. This joint allows for movement in all directions.
The bat wing does not move at the same degrees (360°) as it does not move in all directions - the wing has an up and down movement which is more of a 180° movement and not a 360° movement.
what will happen to energy levels in an ecosystem if the water cycle is disrupted
Answer:
Okay if the water cycle is disrupted ...the energy levels in an ecosystem will decrease
Explanation:
This is mainly because water is mainly used in energy recyclability and so that water is converted to energy through the ecosystem and the presence of water makes the energy to be there in adequate and so if the water cycle is disrupted the energy will decrease
Researchers are investigating the incidence of algal blooms in neighborhood ponds. In summer, they collect water samples from over 100 neighborhood ponds in Dallas, Texas and surrounding cities. They also surveyed residents in each neighborhood to collect data such as average lot size, average home value, average resident income, and lawn care methods. The researchers found that neighborhoods with large lots, high home values, and high income levels were likely to use automatic sprinklers and synthetic fertilizers on their lawns. These same neighborhoods were very likely to have abundant algae in their ponds. Based on this research, which conclusion provides the best explanation for why algae proliferate in neighborhood ponds?
Answer:
Excessive synthetic fertilizer that washes into ponds may be the reason for which algae become so abundant.
Explanation:
Algal blooms that feed on fertilizers can deplete oxygen in water, thereby producing inhospitable ponds. In this regard, it has been shown that the runoff of fertilizers from farms (which are rich in nitrogenous matter) may cause algae to become abundant in coastal environments, depleting oxygen in the water and killing the living organisms that inhabit these areas.
I'm dropping out
I'm tired of University, I'm sick of all my professors for treating me harshly especially during these hard times, and I hate taking midterms.
I'm currently a college freshman in the middle of the semester, and things have been pretty tough. I've been procrastinating the whole week because I had everything going on and I couldn't keep up. I'm a biology major (pre-med) and I have to take two science classes. I suck at managing time and I suck at studying. I feel like I cannot do this. Also, whenever I do my assignments, my professors grade so friggen harshly & give me unfair grades even though I work all the way through midnight finishing it.
I'm a good student, it's just that you know some people can be burned out. I am burned out and college has just been draining my soul each day. Should I drop out?

In living organisms, lipids function mainly as
A) sources of stored energy and transmitters of genetic information
B) transmitters of genetic information and catalyst of chemical reactions
C) catalysts of chemical reactions and components of cellular membranes
D) sources of stored energy and components of cellular membranes
BRAINLIEST FOR CORRECT ANSWER
In living organisms, lipids function mainly as sources of stored energy and components of cellular membranes, which are present in Option D, as lipids are a diverse group of molecules that perform various functions.
What are lipids?Lipids can be broken down through a process called hydrolysis to release energy that can be used for cellular processes, and this energy storage is particularly important for organisms that need to survive for extended periods without a steady supply of nutrients, lipids also play a crucial role in forming the cellular membrane that surrounds and protects cells, such as the phospholipid bilayer, which is a key component of cellular membranes and is made up of two layers of phospholipid molecules.
Hence, in living organisms, lipids function mainly as sources of stored energy and components of cellular membranes, which are present in Option D.

Assume cube B was broken into many irregularly shaped pieces. Compared to the density of the entire cube, the density of one of the pieces would be
Answer:The same
Explanation: even thought the cube is split in many pieces the density stays the same
Because breaking the thing into pieces divides the mass and volume by the same factor, the density does not change. Additionally, regardless of a substance's size, its density is constant.
What is density relation with shape of object?An intensive property is density. This implies that the density of the substance will remain constant regardless of the shape, size, or amount of the thing.
Each component of the thing would have the same density even if you divided it into a million pieces.
For instance, despite the cube being divided into numerous parts, its density remains constant.
In a solid, the atoms or molecules are typically arranged in an orderly or occasionally crystalline structure,
Whereas in a liquid, they are free to move around with little restrictions. Because of this, the solid has a higher density.
Therefore, the density of one of the pieces is remained unchanged.

The sequence is >> Met-Val-Ser-Thr-Lys-Leu-Phe-Asn-Glu-Ser-Arg-Val-Ile-Trp-Thr-Leu-Met-Ile, or abbreviated M-V-S-T-K-L-F-N-E-S-R-V-I-W-T-L-M-I
Explanation:
Trypsin is a serine protease enzyme capable of hydrolyzing different types of proteins. This enzyme is used in biotechnology and molecular biology to hydrolyze at the carboxyl side of arginine or lysine residues. Moreover, chymotrypsin is another digestive protease that also catalyzes the breakdown of proteins into small polypeptide chains. This enzyme cuts the C-terminal side of aromatic amino acids such as tryptophan (W), tyrosine (Y) and phenylalanine (F) on peptide chains.
