Answer: if the upper leg muscles were damaged, (You would not be able to extend the leg straight).
Explanation:
The upper leg muscles, which can also be called the thigh, are made up of three sets of muscles which include:
--> the hamstring muscles: These are located at the BACK of the thigh. They are made up of three long muscles which includes the semimembranous muscle, the semitendinosus muscle, and the biceps femoris muscle.
--> the quadriceps muscles: They are located at the FRONT of the thigh. They consists of four individual muscles which includes the three vastus muscles and the rectus femoris.
--> the adductor muscles: They are located at the medial compartment of the thigh and is consist of the following muscles: gracilis, obturator externus, adductor brevis, adductor longus and adductor magnus.
The quadriceps, hamstrings and adductor muscles work together to straighten (extend) and bend (flex) the leg. Therefore when there is damage to the upper leg muscles, you would not be able to extend the leg straight.

The growth of the plants that the animal used for food could not keep up with the needs of the population. There was so little food for the animals, the population declined. How does this relate to carrying capacity?
Answer:
Carrying capacity can be defined as a species' average population size in a particular habitat. The species population size is limited by environmental factors like adequate food, shelter, water, and mates. If these needs are not met, the population will decrease until the resource rebounds.
The typical population size of a species in a given habitat is referred to as carrying capacity. Environmental elements including sufficient food, shelter, water, and mates are able to control the population number of the species.
What is Carrying capacity?The greatest number of a distinct organisms that can be supported by a particular environment, considering the food supply, habitat, water, as well as other resources, is known as the carrying capacity of that ecosystem.
The typical population size of a species in a given habitat is referred to as carrying capacity. Environmental elements including sufficient food, shelter, water, and mates are able to control the population number of the species. The population will decline until the resource recovers if these needs really aren't supplied.
Thus, the typical population size of a species in a given habitat is referred to as carrying capacity.

Which kingdom contains organisms that are multicellular, heterotrophic, eukaryotic, and lack cell walls?
Animalia
Protista
Plantae
Fungi
Organisms that are multicellular, heterotrophic, eukaryotic, and devoid of cell walls are found in the kingdom Animalia.
Which creatures fall within the Animalia category?All living things fall under the Metazoa, also known as the Kingdom Animalia. This kingdom lacks prokaryotes and protists (Kingdom Monera contains bacteria and blue-green algae) (Kingdom Protista, includes unicellular eukaryotic organisms).
As to why Animalia is a kingdom?Kingdom Animalia is a taxonomic kingdom that includes both extant and extinct species of animals. Eukaryotic, multicellular, heterotrophic, without a cell wall, and largely motile describe the members of this kingdom. They all have numerous cells and are heterotrophs, which means they rely on food from other living organisms.

A porcupine eats 3,000 J of plant material. Of this, 2,100 J is indigestible and is eliminated as feces, 800 J are used in cellular respiration, and 100 J are used for growth and reproduction. What is the approximate production efficiency of this animal?A) 3%B) 11%C) .03%D) 27%E) 33%
Answer:
A) 3%
Explanation:
Given;
total energy consumed by the porcupine, [tex]E_t[/tex] = 3,000 J
energy eliminated as feces = indigestible plant energy, = 2,100 J
internal energy for cellular respiration = 800 J
energy used by the animal for growth and reproduction = production energy of the animal = 100J
The approximate production efficiency of this animal is calculated as;
[tex]E_n = \frac{100 \ J}{3,000 \J} \times 100 \%\\\\E_n = 3.33 \%\\\\E_n \approx \ 3\%[/tex]
Therefore, the approximate production efficiency of this animal is 3 %
Scientists now classify all living things into 6 kingdoms. Which of the following groups of organisms is classified into the greatest number of kingdoms?
A. multicellular animals that are larger than humans
B. humans and other multicellular organisms that are about the same size as humans
C. plants and animals that are smaller than humans but still visible
D. organisms that are microscopically small and each made of a single cell
humans and other multicellular organisms that are about the same size as humans.
What are 6 kindgoms?
The greatest classification for all organisms in biological taxonomy is called a kingdom. In taxonomy, there are 6 kingdoms. These six kingdoms comprise all forms of life. Eubacteria, Archae, Protista, Fungi, Plantae, and Animalia are the six kingdoms.
Most scientists believed that all living things could be categorized as either plants or animals up until the 20th century. However, most biologists realized in the 1950s and 1960s that this approach was insufficient for fungus, protists, and bacteria.
A classification scheme known as the "Five Kingdoms" came to be acknowledged as the standard by which all living things may be arranged by the 1970s.
Therefore, humans and other multicellular organisms that are about the same size as humans.

Although the number of genes in the human genome is surprisingly low compared to less complex organisms, the number of possible products from those genes is greatly amplified by _____.a. coordinate control of genes on different chromosomesb. alternate arrangements of exons from a primary transcriptc. differential activation of genes in different cell typesd. each gene being activated by a unique combination of control elements and activator moleculese. the congregation in specific sites in the nucleus of genes involved in related metabolic processes, but on different chromosomes
Answer:
alternate arrangements of exons from a primary transcription.
Explanation:
Genomics refers to the scientific study of genes (DNA) found in living organisms such as humans and animals.
A genome can be defined as the complete set of hereditary instructions that is typically found in the deoxyribonucleic acid (DNA).
Genome imprinting can be defined as an epigenetic biological process in which a genomic domain or genes of a living organism is marked biochemically with information that is related to parental origin. Thus, it is a non-Mendelian inheritance i.e genome imprinting is typically independent of Mendelian inheritance.
Transcription can be defined as a process which typically involves re-writing the informations contained within a Deoxyribonucleic Acid (DNA) into a Ribonucleic Acid (RNA) by enzyme RNA polymerase.
Although, the number of genes contained in the human genome is surprisingly low in comparison with less complex organisms such as bacteria, protozoa, salmonella, etc.
However, the number of possible products from those genes is greatly amplified by alternate arrangements of exons from a primary transcription.
An exon refers to the coding portion of a gene that contains the information required for transcribing and translating (encoding) the final part of a mature RNA, after one or more DNA sequences (introns).
Simply stated, an exon is a nucleotide sequence in DNA and RNA used for encoding a part of the final mature RNA.
A nucleotide can be defined as an organic molecule which forms the building block of nucleic acid such as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).

I need a Multiple Alleles trait for an animal!!!
Answer:
Fury can be a allele trait in an animal anything that you can see in the physical appearance on the animal can be a alleles trait
Answer:
Anything you see physically on an organism can be considered as an allele.
Explanation:
An allele is one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.
Let's use one example: a white bunny with red eyes. One allele for this animal would be that it has white fur color. Another allele would be its red eye color.
Let's use another example, but with two people. Person A has straight hair and freckles. Person B has curly hair and no freckles. Person A's alleles would be straight hair and freckles. Person B's alleles would be curly hair and no freckles.
Any physical characteristic trait on an organism can be considered as an allele for that organism.

Please correct me if im wrong
The endocrine system generally uses negative feedback to maintain homeostasis. true.
The endocrine systemThe endocrine system has the function of coordinating and integrating the activity of cells throughout the organism by regulating cellular and organic functions and by maintaining homeostasis (maintenance of a constant internal environment) throughout life.
Negative feedback is one of the most important mechanisms for maintaining our body's homeostasis, that is, for internal balance. This mechanism guarantees an opposite change in relation to the initial alteration, that is, it produces responses that reduce the initial stimulus.
Whit this information, we can conclude that the endocrine system generally uses negative feedback to maintain homeostasis.
