how does the cytoskeleton help maintain cell shape?
Answer:
Of the three types of protein fibers in the cytoskeleton, microfilaments are the narrowest. ... Microfilaments also provide some rigidity and shape to the cell. They can depolymerize (disassemble) and reform quickly, thus enabling a cell to change its shape and move.

Trilobites
Trilobites were crab-like animals
that lived in ancient seas.
Scientists have discovered many
trilobite fossils all over the world.
However, the fossils only appear
in rocks that are at least 250
million years old. In more recent
rocks, their fossils are absent.
1. What conclusion would you
draw about trilobites based on
their appearance and
disappearance in the fossil
record
Answer:
The trilobites probably disappeared because either: A) they evolved into something else, or B) they died out due to the amounts of land rising out of the ocean.

Why does it take longer for your body to break down complex carbohydrates than simple carbohydrates?
Explanation:
complex carb pack more nutrients are simple carbs that are high in fiber and digest more slowly this makes them more ceiling which means a good option to for weight control
The small intestine is where carbohydrates are chemically broken down, instead of the stomach. The disaccharides and pancreatic amylase complete the chemical cleavage of digestible carbs.
What are the complex carbohydrates in the body?The building blocks of large polysaccharides are lengthy, complicated chains of sugar molecules.
Peas, beans, whole grains, and vegetables are examples of foods that are sources of complex carbohydrates. The body converts simple and complex carbohydrates into glucose (blood sugar), which is then used as fuel.
Longer-lasting blood glucose increase and longer-lasting energy elevation are produced by complex carbs.
Therefore, complex carbs are more efficient in giving the body energy, which is the main purpose of carbohydrates.

Marcus is hanging a porch swing on his front porch. The first thing he has to do is attach two springs to the ceiling. Then, he fastens the
swing to the springs so that they can stretch and support the weight of the swing. Which two types of potential energy do the springs have?
A. elastic
B. gravitational
C. kinetic
D. stretched
The two types of potential energy that the springs have when Marcus hangs the porch swing on his front porch are (A)elastic potential energy and (B)gravitational potential energy.
The elastic potential energy is stored in the springs due to their deformation from their natural state. The gravitational potential energy is stored in the swing due to its height above the ground, which is determined by the position of the springs.
When Marcus attaches the springs to the ceiling, the springs are stretched and deformed from their natural state. As a result, they store elastic potential energy. This energy is proportional to the amount of deformation, which in turn is proportional to the weight of the swing and the distance the springs are stretched.
When Marcus fastens the swing to the springs, the gravitational potential energy of the swing is determined by its height above the ground. The higher the swing is from the ground, the greater its gravitational potential energy. The swing's height is determined by the length of the springs and their position relative to the ceiling
Therefore, the correct answers are A. elastic potential energy and B. gravitational potential energy.

What is the complementary strand of DNA that is made during DNA replication if the template/parent strand of DNA reads ATG GGC CAT?
A. TAC CCG GTA
B. UAC CCG GUA
C. ATG GGC CAT
D. CGA AAT AGC
The complementary strand of DNA that is made during DNA replication if the template/parent strand of DNA reads ATG GGC CAT is TAC CCG GTA. Thus, the correct option for this question is A.
What is DNA replication?DNA replication may be defined as a type of biological process through which two identical replicas of DNA form from one original DNA molecule. This process makes a copy of the DNA in a cell is made before the cell divides.
When it comes to the complementary strand of DNA, either of the two chains makes up a double helix of DNA, with corresponding positions on the two chains being composed of a pair of complementary bases.
For example, if Adenine A is present in the parental DNA, then it should be complementarily bounded to the thymine and vice versa. Similarly, if Cytosine is present in the parental strand of DNA, then it should be complementarily bounded by guanine and vice versa.
Therefore, the correct option for this question is A.

Co..me up with your own example of a stimulus and response with living organisms
.
Answer:
A crocodile goes into the shade when the temperature goes high.
An example of a stimulus and response with living organisms is as follows:
Whenever any living organism is exposed to a warm or hot object it immediately pulls back its own body from this point of contact. This is also called as reflex action. What is a Stimulus?A stimulus may be defined as a type of thing or event that immediately provokes a specific functional reaction by an organ or tissue in response to a specific treatment.
The information that living organisms perceive from the external world is sensed by the sense organs then with the help of nerves it sends to the brain which stimulates a specific action and sends messages to the body to react in a particular way with the respect to the stimulus.
Therefore, an example of a stimulus and response with living organisms is briefly mentioned above.

During an experiment, if you purposely change the temperature to test a hypothesis, the temperature is called the a. manipulated variable. b. responding variable. c. hypothetical variable. d. dependent variable.
Answer:
Option a (manipulated variable) would be the appropriate choice.
Explanation:
To analyze the influence on something like a dependent variable, another modified variable seems to be an important variable responsive to modifications in quite an analysis. Plainly defined, the variable has been adjusted to determine its effect on the overall outcome of the study. There would be only one manipulated component in a correctly planned analysis.The other options offered are not relevant to the situation described. So, the solution above is the best one.

what is the biodiversity score of farmland (maize)?
Answer:
Required Answer:-The intensification of agriculture has caused dramatic declines in farmland biodiversity (Carvalheiro et al., 2013; Senapathi et al., 2015). Since the 1990s, agricultural policies have been developed in Europe to mitigate this loss through agri-environmental schemes (AES). One AES is “sown wildflower strips”, the aim of which is to create new ecological infrastructures by sowing attractive wild flowers on arable land (a few % of the cultivated area). These ecological infrastructures fall within our definition of MIMS since they represent a massive introduction of managed species in the landscape.

Transverse waves are always characterized by particle motion being perpendicular to wave motion. A longitudinal wave is a wave in which particles of the medium move in a direction parallel to the direction that the wave moves.
Answer:
The given statements are True.
Explanation:
The particle of the matter through which a wave move or travels is called medium. The mechanical waves can be distinguished into three types on the basis of the movement of the medium when the energy of the mechanical wave passes through, are: transverse, longitudinal, and surface waves
A transverse wave: perpendicular to the direction that the wave
A longitudinal wave: parallel to the direction that the wave
where do veins always go
Answer:
Capillaries connect the arteries to veins. The arteries deliver the oxygen-rich blood to the capillaries, where the actual exchange of oxygen and carbon dioxide occurs. The capillaries then deliver the waste-rich blood to the veins for transport back to the lungs and heart. Veins carry the blood back to the heart.
