To solve this, we must be knowing each and every concept related to speed, acceleration and its calculation. Therefore, the given statement is false.
What is speed?Speed may be defined as the distance traveled by an item in the amount of time it requires to travel that distance. In other words, it measures how rapidly an item travels but does not provide direction. The term "velocity" refers to the combination of direction and speed.
Acceleration is defined by the rate at which an object's velocity changes with respect to time. When an object's velocity changes, it is referred to as accelerating or to have acceleration. Speed does not include the direction of an object's motion. Acceleration include the direction of an object's motion.
Therefore, the given statement is false.

The trait for tall pea plants is (T) and the trait for short pea plants is (t). The trait for smooth pea plants is (R) and the trait for wrinkled is (r).Two plants are crossed producing a F1 generation of plants with 612 tall and smooth pea plants and 188 short and wrinkled pea plants.What would be the most likely genotype of the parental generation?
Answer:
P generation = TtRr × TtRr i.e both parents were heterozygote for both traits
Explanation:
This question involves two genes encoding the height and texture in pea plants respectively. The alleles for tall and smooth pea traits are dominant over the alelles for short and wrinkled traits.
According to this question, two plants are crossed to produce F1 offsprings as follows: 612 tall and smooth pea plants and 188 short and wrinkled pea plants.
First, we turn this derived number of offsprings into ratio by dividing by the smallest number (188)
612/188 : 188/188
3.25 : 1
Approximately; we can say this is 3 (tall and smooth) : 1 (short and wrinkled)
Based on this ratio, which was got by Mendel for his F1 offsprings when he crossed pea plants, the parental generation has a heterozygous genotype (TtRr).

Which of the following describes a non-sense mutation?
A.Base pair change results in a premature stop codon; protein is nonfunctional.
B.Base is changed but the resulting amino acid is the same as in the non mutant DNA. No outward changes
.
C.A base is either added or deleted and causes the codons to be read incorrectly.
D.Base pair change results in a different amino acid; this may or may not affect the protein that result.
Answer:
A.Base pair change results in a premature stop codon; protein is nonfunctional.
Explanation:
Mutation, generally, refers to any change that occurs to the genetic sequence of a DNA. It can occur in different forms, hence, has different types. One particular type is the base pair substitution mutation, which involves the replacement of one or more nucleotide base by another in a sequence.
Base pair substitution can either result in one of the following namely: silent, missense, and nonsense. In NONSENSE mutation, the replacement of bases in the sequence causes the translation process to stop because a STOP CODON is prematurely encountered. Hence, the protein is non-functional.

Explanation:
Evergreen trees are plant tree species that remain green across seasons, even in cold/dry conditions, thereby contrasting with deciduous trees that lose their leaves in cold/dry conditions. Conifers (Coniferophyta) are gymnosperm plants that produce seeds without fruit/flowers. Conifers are vascular land plants composed of one that one class named Pinopsida, which consists of perennial plants with secondary growth. Moreover, mango, elm, and maple are hardwood trees that have seeds within fruits (i.e., they are angiosperms), which lose their leaves seasonally (i.e., they are deciduous trees).
Describe the movement of oxygen molecules if there were more oxygen molecules
outside the cell
Explanation:
Because there's a higher concentration of oxygen molecules outside the cell compared to the cell's cytoplasm, you'll see that oxygen diffuses into the cell along this concentration gradient. ... Because the molecules are moving at random, some will move out of the cell, but most will be moving in in this case.
Transporation is the mechanism by which the molecules and enzymes move in and out of the cell. When more oxygen is present outside the cell diffusion will occur along the concentration gradient.
What is diffusion?Diffusion is a transportation mechanism that involves the movement of the ions and the molecules from the high concentration area towards the low concentration region.
The high amount of oxygen present outside the cell will diffuse through the cell membrane inside the cell along the concentration gradient so that the concentration inside and the outside achieves equilibrium.
Therefore, the movement of the oxygen molecules from high concentration to low is diffusion.

A Class-A 10 mL pipette is supposed to dispense 10.00 mL of water. A lab technician makes three measurements of the volume that the pipette actually dispenses, and obtains volumes of 9.70 mL, 9.69 mL, and 9.71 mL. The pipette is:__________
a) Accurate, but not precise
b) Precise, but not accurate
c) Accurate and precise
d) Neither accurate or precise
Answer:
d) Neither accurate or precise
Explanation:
Accuracy and precision are critical factors in the experimental procedure. Accuracy can be defined as the amount of uncertainty in the process of measurement in relation to the true value (in this case, 10 mL). On the other hand, precision is an independent feature of the accuracy which indicates the repeatability of the measurement process (in this case, three measures weren't repeated). Therefore, precision indicates the confidence of a particular measurement, while accuracy indicates how close is this value to the real value.

Note: The question is incomplete. The complete question is found in the attachment below.
Explanation:
High temperatures or changes in pH can denature an enzyme, causing it to lose its shape and activity.
Enzymes speed up chemical reactions by lowering the activation energy which allows the reaction to proceed much more quickly.
An enzyme is considered a(n) catalyst because it speeds up a chemical reaction without being used up.
The induced fit between an active site and its substrate often strains bonds and helps the reaction proceed.
A(n) inhibitor is a molecule that can bind to an enzyme and prevent the enzyme from working.
During an enzymatic reaction, a molecule of substrate binds to the enzyme and is broken down into one or more molecules of product which are released.
The specific location within an enzyme molecule where the substrate binds is called the active site.
Lactose takes years to break down on its own. But if exposed to the protein lactase, the reaction proceeds very quickly, while lactase itself remains unchanged. Lactase is an example of a(n) enzyme.
Wolves that live in snowy climates often prey on rabbits. Some rabbits can move quickly across deep snow because they have large feet that don’t sink into the snow. Rabbits without this adaptation move more slowly across the snow. Which statement best justifies how the rabbit population changes over time?
A. Sea coral would make immediate adaptations through genetic mutations to adjust to the changes in the environment.
B. The ocean water would change its current so that the acidic water is relocated to another area and allow sea coral to survive.
C. The ocean water would change its composition to reduce the amount of carbon dioxide contained and allow sea coral to survive.
D. Sea coral would become extinct because of its inability to make adaptations fast enough to adjust to the changes in the environment
Answer:
It's A
Explanation:
Just like the corals have genetic mutations to adapt to their environment so do the rabbits change their genetic characteristics to make sure the species continue it's lineage by evolving and growing their feet so they can be faster and not sink in the snow, becoming harder preys to catch, otherwise, if their paws were smaller, they would be slower and, therefor, an easy catch for the wolves, probably becoming extinct after awhile.
The statement that justifies how the rabbit population changes over time is sea coral would make immediate adaptations through genetic mutations to adjust to the changes in the environment. So, the correct option is A.
What is Adaptation?Adaptation is the process by which a species becomes fitted to its environment; it is the result of natural selection's acting upon heritable changes.
Rabbits have to change their genetic characteristics same as the coral have genetic mutations to adapt to their environment and to make sure the species continue its downstream by evolving and growing their feet, so they can run faster in the snow and successfully escape from predators. If rabbits are not evolved with an environment that does not favor them, they are surely eliminated from nature.
Therefore, the statement that justifies how the rabbit population changes over time are sea coral would make immediate adaptations through genetic mutations to adjust to the changes in the environment.

A punch is painful, while a hug is not, because a punch produces _______ action potentials from each sensory neuron. A) stronger B) more frequent C) faster-moving D) fewer
Answer:
B) more frequent
Explanation:
This occurs because a punch produces more frequent action potentials from each sensory neuron. This is only caused when there are rapid and sudden changes. A punch is fast and causes very sudden changes when the punch comes into contact with the human body. This therefore, causes these fast and sudden changes which fire very frequently from each sensory neuron. A hug is soft and does not affect the human body in such a sudden way so it does not cause frequent action potentials.

1. Tina is a microbiology student using an HOL kit for her online course. She shares a small apartment with her two cats, and has a full time job across town. Suggest two potential locations in the apartment for Tina to store the lab materials and incubate cultures. Explain why these locations are appropriate choices for Tina.
Answer:
A cabinet and a small closet.
Explanation:
A cabinet and a small closet are the best locations to incubate cultures because these location are safe from the cats interaction with the microbial culture. A cabinet consist of a cupboard with shelves or drawers for storing things. Closet is a tall cupboard which is used for storage things so due to height the cats can't reach to these place so the culture is safe.

Which statements describe functions of antibodies? Select two options.
Answer:
This question lacks options, options are:
A.They maintain the cell’s shape.
B.They regulate cell processes.
C.They protect the body from infectious agents.
D.They signal the immune system to destroy pathogens.
E.They speed up biochemical reactions.
F.They send electrical signals.
The correct answers are C and D.
Explanation:
B cells and T cells use different biological weapons to attack the pathogen. The first secrete proteins called antibodies, which are distributed via the blood or the exposed surfaces to the environment, such as mucous. Antibodies are glycoproteins that circulate in the bloodstream looking for antigens that cause some type of damage to the body. Antibodies recognize and neutralize pathogens in a highly efficient way. Once the antibodies are produced, they remain circulating in the bloodstream for several months, which generates immunity for a long period of time to a certain antigen, in other words, they are capable of recognizing other molecules (antigens) in a very specific way and forming stable complexes with them (immune complexes). Its appearance in plasma is part of the adaptive immune response, in what is known as a specific humoral response, constituting a very effective defense against pathogens.
