Answers

That is false. Physical characteristics of an organism are genetically passed down.

—Evidence—

A characteristic that an organism can pass on to its offspring through its genes.

The set of information that controls a trait; a segment of DNA on a chromosone that codes for a specific trait.

Heredity is the biological process responsible for passing on physical traits from one generation to another.

Answers

Answer:

mutation rates can be used to design molecular clocks in order to estimate divergence times among species  

Explanation:

In evolutionary biology, the substitution rates (also known as mutation rates) are used for the development of 'molecular clocks' which allow estimating the divergence times among species or among taxonomic groups. Molecular clocks can be designed by estimating the divergence rate of nucleotide sequences (either DNA or RNA) and amino acid (protein) sequences. These substitution rates can also be used to track how quickly viruses evolve (for example, in a pandemic situation).

Explanation:

The presence of cilia, flagella and pseudopods improve the chances of survival of a protist by increasing the likelihood of obtaining nutrients. Thus, the correct option is A.

What is locomotion?

Locomotion is the basic act or ability of something to transport or move itself from one place to another. Many protist species have the presence of some type of locomotory organelles on their body which are easily visible under a light microscope. A protists can move by gliding or floating, and by use of organelles such as flagella or cilia.

Protists use these locomotory organelles to find food, a mate, a suitable habitat or to survive and escape form the predators. Types of Movements involved in locomotion include axial and appendicular.

Therefore, the correct option is A.

PHET skate park . Consider this equation: Kinetic Energy = ½ mv2. Which of those variables is changing as the skater moves up and down the track?

Answers

Velocity is the variable which is changing during motion of skater.

Impact of velocity on energy

Velocity is the variable which is changing when the skater moves up and down the track because moving upward on the slope decrease the speed of the skater while on the other hand, velocity increases when moving downward on the slope.

Mass of the body which is skating remain constant or can't change with height. Mass is the amount of matter present inside the body so we can conclude that velocity is the variable which is changing during motion of skater.

You do a serial dilution in the same manner as the one in the video. A plate with a sample volume of 10-6 mL produced 43 colonies. What was the original cell density (CFU)?

Answers

Answer: 43 x 10^6  CFU.

Explanation:

Plate count is a method used to determine the number of viable microorganisms in a sample. When the bacterial concentration is high, serial dilutions are carried out in a 1:10 sequence. Then, the dilutions are successive dilutions keeping the dilution factor constant at each step. Small aliquots of these dilutions are seeded in medium contained in a Petri dish where the bacteria grow forming colonies. Then the plates are incubated and colonies develop both within the agar and on the surface.

If the concentration of the seeded aliquot is too high, the bacteria will grow too much and it will not be possible to distinguish the colonies. However, if the concentration is very low, the number of colony forming units (CFU) may be very low and thus can be counted.

Colony forming units are calculated:

CFU = Number of colonies / (volume seeded on the plate * dilution).

The dilution is 10^-6, the number of colonies counted is 43, and usually the volume plated is 0.1 mL, so we replace that in the equation:

CFU= 43 / (0.1 mL * 10^-6)

CFU= 43000000 = 43 x 10^6

Spend one minute writing an explanation of
the FUNCTION of enzymes. YOU MUST USE
THE WORDS CATALYST, ACTIVATION
ENERGY, RECYCLABLE

Answers

Like all catalysts, enzymes work by lowering the activation energy of chemical reactions. Activation energy is the energy needed to start a chemical reaction. This is illustrated in Figure below. The biochemical reaction shown in the figure requires about three times as much activation energy without the enzyme as it does with the enzyme.

The reaction represented by this graph is a combustion reaction involving the reactants glucose (C6H12O6) and oxygen (O2). The products of the reaction are carbon dioxide (CO2) and water (H2O). Energy is also released during the reaction. The enzyme speeds up the reaction by lowering the activation energy needed for the reaction to start. Compare the activation energy with and without the enzyme

Answer:

Enzymes help speed up chemical reactions in the human body. They bind to molecules and alter them in specific ways. They are essential for respiration, digesting food, muscle and nerve function, among thousands of other roles.

What is the function of an enzyme? They allow chemical reactions to occur at normal body temperature fast enough to sustain life. They reduce the activation energy needed to start a chemical reaction.

There are four steps in the process of an enzyme working. (1) An enzyme and a SUBSTRATE are in the same area. The substrate is the biological molecule that the enzyme will work on. (2) The enzyme grabs onto the substrate with a special area called the ACTIVE SITE.

Enzymes create chemical reactions in the body. They actually speed up the rate of a chemical reaction to help support life. The enzymes in your body help to perform very important tasks. These include building muscle, destroying toxins, and breaking down food particles during digestion.
