Answer:
Captive breeding is generally undertaken when a species has reached critical population levels where risk of extinction is likely. ... Protect the population against disease. Preserve the gene pool to avoid problems of inbreeding. Provide animals to re-establish or restock wild populations when needed.
What are 5 different types of heterotrophs, what do they eat, and give an example of an organism for each category.
Answer:
Five different types of heterotrophs are carnivores, herbivores, omnivores, scavengers, and detritivores.
Carnivores eat the meat of other animals. Example: Bear
Herbivores eat vegetation. Example: Deer
Omnivores eat a combination of both meat and vegetation. Example: Humans
Scavengers eat things left behind by carnivores and herbivores. Example: Raccoon
Detritivores eat small bits of organic matter, such as soil. Example: Worms
Edit: If you'd rather substitute one of those for a decomposer, Decomposers break down dead or decaying organisms. Example: Mushroom, or fungi.
The cell membrane (plasma membrane) is describe as a highly selective
barrier composed of alipid bi-layer. This structure plays an important role
in moving molecules across the cell membrane in order for the cell to
maintain homeostasis. If the cell is unable to take in the materials it needs
or remove vwhat it does not need, the cell may die. This inability of cells to
maintain homeostasis may cause sickness or even death of an organism.
Why is it important that the cell membrane is highly selective?
O So that the cell wall is stabilized and maintains its rigidity.
O To prevent certain ions and molecules from entering or exiting the celI.
O So that proteins and lipids can attach to the membrane where needed.
O To allow movement of materials in and out of the cel.
Answer:
O To prevent certain ions and molecules from entering or exiting the celI.
Explanation:
The cell needs to keep a constant chemical composition on the inside in order to mantain homeostasis
A plant uses sunlight to make its food. What kind of energy transition is
taking place?
O A. Sound energy to heat energy
B. Mechanical energy to light energy
C. Light energy to chemical energy
D. Chemical energy to heat energy
Answer:
I don´t correctly remeber this part of science, but i am going to take a guess and say D) Chemical energy to heat energy
Explanation:
Answer: I believe it is C. Light energy to chemical energy.
Explanation: I think it is C. because this process is photosynthesis which is the process of taking sunlight (which would be light energy) and making oxygen and glucose (which I think would be chemical energy).
Describe how transposable elements create mutations within an organism and how transposable elements facilitate chromosomal rearrangements.
Answer:
Transposable elements are discrete segments of DNA that can be excised and reintegrated to another site in the genome, these can inactivate the gene in which they reside, cause chromosome breaks, and / or transpose to a new location within the genome.
Explanation:
Transposable elements are fragments of DNA that have the ability to jump from one part of the genome to another. While most of the DNA is always in the same place surrounded by the same neighboring pieces of DNA, mobile elements move from one place to another causing many changes or mutations. When a transposon moves through the genome, it can insert into a vital gene, disrupting its function, or into a location near vital genes, causing erroneous activation or inactivation.On the other hand, there can be chromosomal rearrangements due to transposons of the same family with complementary sequences that are separated in the genome and that by sequence homology match. This can lead to ectopic recombination. Large-scale rearrangements induced by mobile elements are considered a particular class of recombination events that influence genomic plasticity.

Answer:
Which of the following statements about exponential growth curves is true?
- a. Exponential growth curves are common for R-selected species.
Explanation:
The statement that is true about exponential growth curves is as follows:
Exponential growth curves are common for R-selected species.Thus, the correct option for this question is A.
What is an Exponential growth curve?An Exponential growth curve may be defined as a type of growth curve that significantly illustrates greater increases in the population of organisms with respect to time. It immediately represents the growth with extreme fast rates.
Exponential growth is followed by the continuous breeding population which contains more individuals than a similar population breeding annually. It includes examples like some insects, r-selected species, etc.
The shape of the exponential growth curve is J-shaped. It represents only fast growth rates. While the logistic growth curve shows fast growth rates followed by slow growth rates. It possesses a shape known as S-shape. It represents the growth rate of k-selected species.
Therefore, the correct option for this question is A.

replicate the following dna strand TAT-TAG-ATT-ACA
The replication of the given DNA strand TAT-TAG-ATT-ACA is ATA-ATC-TAA-TGT.
What is DNA replication?DNA replication may be defined as a type of biological process through which the genomic DNA of an organism gets copied into the cell during the time of cell division. During this process, the two identical replicas of DNA are produced from one original DNA molecule.
According to the context of this question, when it comes to DNA replication, adenine is replaced by thymine and vice-versa while guanine is replaced by cytosine and vice-versa. So, the amount of adenine remains equal to the amount of thymine and the amount of guanine remains equal to cytosine.
Therefore, the replication of the given DNA strand TAT-TAG-ATT-ACA is ATA-ATC-TAA-TGT.

Are the fatty acid tails saturated or unsaturated?
and What type of lipid is shown in the picture?
Answer:
The fatty acid tails saturated or unsaturated is discussed below in details.
Explanation:
Fatty acids contain a carboxylic acid association and a great hydrocarbon series, which can either be saturated or unsaturated. A saturated fatty acid tail only contains carbon-carbon individual bonds, and an unsaturated fatty acid has at the slightest individual carbon-carbon twice or triples bond.

Which event in meiosis increases genetic variation within a population?
A. DNA condenses to form chromosomes.
B. Segments of chromosomes cross over.
C. Chromosomes duplicate themselves.
D. Chromosomes form pairs.
Answer:
Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. This produces a unique combination of genes in the resulting zygote. Recombination or crossing over occur during prophase 1

Scenario 1
When you think of the American Southwest, you probably think of cacti, both big and small. If you were to
visit the American Southwest today, you might be disappointed with the lack of variation among cactus
species, especially right off the major highways. In 1926, Route 66 was the nation's first major highway to
allow visitors to visit the Southwest. Like many tourists, these visitors wanted to take home a memento of
their travels. Many people would pull over and begin looking for their own living souvenir. Since many of the
tourists did not have the necessary tools to extract a spiny cactus out of the soil, they usually had to make a
conscious decision about what type of cactus they should dig up. The cacti with too many spines were seen
as too difficult to dig out, and the visitors likely didn't have gloves to protect their hands. The cacti with too
few spines were seen as homely and were often overlooked. Therefore, the tourists found a cactus that was
between these two extremes. Over the last century, the phenotypic variation within these small cacti has
changed (at least in areas accessible by these highways).

access the capabilities of animal and plant cell types owing the presence or absence of chloroplast and cell wall
Answer:At this point, it should be clear that eukaryotic cells have a more complex structure than do prokaryotic cells. Organelles allow for various functions to occur in the cell at the same time. Despite their fundamental similarities, there are some striking differences between animal and plant cells (see Figure 1).
Animal cells have centrosomes (or a pair of centrioles), and lysosomes, whereas plant cells do not. Plant cells have a cell wall, chloroplasts, plasmodesmata, and plastids used for storage, and a large central vacuole, whereas animal cells do not.
