What structures allow each protist to move?
Amoeba:
Euglena:
Paramecium:
Amoeba moves using pseudopodia.
Euglena moves using flagellum.
Paramecium moves using cilia.
What are the structures that allow the movement in different protists?
Pseudopodia, or protruding portions, are used by amoebas to move. Its meaning is "false feet." These are membrane elongations of the cell. With its pseudopod, an amoeba can reach out and grab a surface, using it to propel itself forward.Flagellums (plural flagella), a long whip-like structure that functions as a little motor, help euglena move. On the anterior (front) end, the flagellum spins in order to propel the cell through the water.Cilia have the ability to move in unison to advance a Paramecium. When a barrier is reached, the cilia travel in the opposite direction, somewhat reversing the Paramecium's forward motion.

Describe how a protein would be changed if a base sequence mutates
from GGA to TGA.
Answer:
The protein would contain threonine instead of proline
Explanation:
The shape of the protein may be changed when a base sequence mutates from GGA to TGA.
What do you mean by Mutation?A Mutation may be defined as a sudden, stable, and inheritable change that occurs in the genetic material of an organism.
The amino acid sequence would be different, as GGA codes for Glycine, while UGA or TGA codes for stop codon which terminates the process of protein synthesis.
The protein which may be synthesized may not work correctly. In other words, the protein would be functional less.
Therefore, the shape of the protein may be changed when a base sequence mutates from GGA to TGA.

(c) Based on the data in Figure 1, describe whether or how the size of the leopard population appears to have been affected by the lion population over the period for which data were analyzed. The scientists also estimated the consumed biomass of the prey animals of the leopards and lions. They estimated that the lions annually ate a total of approximately 175,000 kg of prey animals. This included approximately 110,000 kg of very large animals. Calculate, to the nearest whole number, the percent of the total biomass eaten by the lions that is composed of very large animals.
Answer: 62.9%
Explanation:
Figure one is not available so I cannot answer the first part of the question.
The second part however, has the relevant information required.
The percentage of large animals eaten by lions from the total amount of biomass eaten by lions is:
= Weight of large animals / Total weight of animals eaten by lions * 100%
= 110,000 / 175,000 * 100%
= 62.9%
Why is it necessary to genetically engineer the bacteria to produce insulin instead of inserting the insulin gene in humans?
Answer:
????????????????
Explanation:
RDNA technology made it possible for bacteria to express an insulin gene from humans for production of insulin synthetically.
What is recombinant DNA technology?Alteration of genetic material from one organism to another, to obtain desired and enhanced genetic characteristics in recombinant organism, is called as recombinant DNA technology.
In this method different genetic material from different organisms can be combined to develop desired characteristics, for example, DNA from two different species is joined together, and the recombinant DNA molecule is then inserted into host organism to produce new genetic combination with higher medicinal, scientific or agricultural values.
Genetically modified bacteria are used for production of human insulin, which cause less immune reactions as compared to the pig or cow version of insulin.

offspring?
A. Mutation that occur during crossing over during the prophase stage of mitosis
B. Mutations that occur in both DNA strands synthesize do the S-phase of mitotic cell cycle
C. Mutations that involve translocation of chromosomes in gametes
during meiosis
D. Mutations that occur in Somatic cells During cell division
Mutations that involve the translocation of chromosomes in gametes during meiosis are likely to be passed to offspring (Option C). It is because mutations are inherited from germinal cells.
Mutations and MeiosisMeiosis is a cell division by which a cell produces four daughter germinal cells having half of the genetic material.
Moreover, a mutation is any alteration in the genetic material of the genome of an organism.
Germinal mutations can be inherited because they occur in the germinal meiotic cells, whereas mitotic (somatic) cells are not inherited.

Microtubules and microfilaments are elongated structures that cross the cell, giving support to the cell, and carries organelles and objects throughout the cell. Their supporting structure would be most like which system of a multicellular organism?
Answer: Their supporting structure would be most likely the MUSCULOSKELETAL SYSTEM of the multicellular organisms.
Explanation:
The musculoskeletal system found in multicellular organisms are made up of structures which provides support, protection and allows for various movements. These structures include:
--> Muscles
--> Cartilage
--> Ligaments
--> Tendons and
--> Joints
Furthermore, Microtubules and microfilaments are the major components of cytoskeleton. They are the structures that gives a cell it's shape and helps organise it's parts. As described in the question, they are elongated structures that cross the cell, giving SUPPORT to the cell, and carries organelles and objects throughout the cell.
Therefore, since the Microfilaments and Microtubules provides support and shape at the cellular level it can be most likened to the musculoskeletal system of multicellular organisms which performs the same functions.

6. Which marrow was denser (had more mass in the given volume)? What impact would that have on the overall density of the bone?
Answer:
The beef bone marrow was denser than the chicken bone because it had more mass in the given volume. Since the chicken must fly, it cannot have its bones weighing it down on the land. However, cows must find grass on land and travel long distances. This would increase the overall density of the bone.
