In other words, how are we speeding up the effects of the competitive exclusion principle and thereby altering the outcome of that ecosystem's natural succession
Answer: Overgrazing, overfishing, and forest fires
Explanation:
Competitive exclusion principle two species which have the same ecological niche cannot exists together as such species will be competing for the same resources. The species which is superior over the other will receive the resources and the other species having no competitive advantage will not survive in future.
According to the given situation, human being is the most superior species on earth and have competitive advantage of thinking ability and intelligence over other species. Succession are the changes that occur in the biotic community of an ecosystem with respect to time.
The human beings can speed up the effects of the competitive exclusion principle by various ways: Overgrazing, overfishing, and forest fires. The overgrazing of the cattle in the field can remove the vegetation cover of the region and the land will become barren so instead of progressive succession in terms of vegetation cover the succession will again re-initiate in terms of primary succession if environment supports.
Overfishing can cause the exclusion of some valuable species of fish and there will not be evolution of such species and will alter the outcome of natural succession.
Forest fires can affect both floral and faunal species some species may tolerate the fire and will survive and some precursors like roots of the plants can support new individual plants. This will again alter the outcome of natural progressive succession in an ecosystem.

Drag the inputs and outputs of cellular respiration to their correct
place.
Answer:
Inputs are: Glucose
Output are; carbon dioxide, ATP and heat
Explanation:
Cellular respiration is the metabolic process by which cells of living organisms breakdown glucose molecules to release energy (ATP). Cellular respiration, which is a must for every living organism uses oxygen (aerobic) to break down glucose (C6H12O6) into carbon dioxide (CO2) and water (H2O).
Based on the question asked, the inputs of cellular respiration are GLUCOSE AND OXYGEN while the outputs are CO2, H2O, ATP and HEAT give out. The general chemical equation is as follows:
C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP
This tutorial will take you step by step through the question.
In cucumbers, dull fruit (D) is dominant to glossy fruit (d), and orange fruit (R) is dominant to cream-colored fruit (r). The gene that codes for dull versus glossy assorts independently from the gene that codes for orange versus cream-colored. A plant that has dull and orange fruits is crossed to a plant that has dull and cream-colored fruits. The cross produces eight total progeny, with three plants that have dull and orange fruits, three plants with dull and cream-colored fruits, one plant with glossy and orange fruits, and one plant with glossy and cream-colored fruits.
Determine progeny phenotypic ratios - texture. To determine the actual genotype of the parents from among the possible genotypes identified in the previous step, separate the cross into two single-locus crosses, looking at the inheritance of each trait by itself. Start with the texture characteristic.

4. Take a beaker (jar or jug) with some water and put some drops of red or blue
ink in it. Take a tender twig of any flowery plant with leaves and flowers, preferably
white flowers, and put it in the beaker for 6 to 8 hours. What do you observe? For
further examination cut across its stem and look for the presence of colored water.
Explain your observations.
Answer:
Blue Ink patches are observed on the leaves of the plant. Also, on cutting across the stem of the plant, the red color of the solution is found along the length of the stem.
The above observation shows that the stem of the plant conducts water through its length to the leaves of the plant.
Explanation:
The leaves of plant obtain water and minerals from the soil through the roots of the plant. The water is conducted by the stem of the plant from the roots to the leaves of the plant where they are needed for photosynthesis as well as for cooling the plant. The xylem tissue in plants is responsible for conducting water to the leaves of the plant from the roots of the plant through the stem.
The conduction of water from the roots to the leaves of the plant is maintained by capillary action as well as by transpiration pull. Transpiration pull refers to the pull of water by the transpiration action taking place in the leaves of the pant, whereby water evaporates from the leaves of the plant through the opening in the leaf of the plant.
When the blue ink is added to the water, the colored water is conducted through the stem of the plant to the leaves. On getting to the leaves, the water molecules evaporate leaving behind the colored patches fond on the leaves. When the stem of the plant is cut, the blue color is seen along its length showing that the colored water was conducted through it.

The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. In this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells
Mr. Morales is teaching a lesson on classification. He says that spiders are classified as a different group than insects because they have eight legs instead of six legs. He explains that spiders evolved first. Mr. Morales also says that having eight legs is the derived trait that separates the two groups. Antonio thinks Mr. Morales is wrong. Which piece of information is Antonio considering?
A.Spiders do not have eight legs.
B.Insects do not have six legs.
C.If spiders evolved first, six legs is the derived trait.
D.Spiders do not have derived traits, since they evolved first.
Answer: The answer is C
Explanation:
The piece of information that Antonio is considering is that if spiders evolved first, six legs are the derived trait. So the correct option is C.
What are derived traits?A trait that has been observed in a group of organisms but was not observed or was absent in the previous common ancestor of the group.
These are also the traits that are not present in the group of organisms under consideration but were observed in the previous common ancestors. This is called the secondary loss of traits.
Therefore, derived traits are not only concerned with the development of new traits but also the loss of old traits. Simplicity in a structure or function is a secondary derived trait.
Thus, because the spiders evolved before other insects, the presence of 6 legs in insects is a secondary derived trait as it represents simplicity in structure. Spiders are not derived because they are the common ancestors of the group of insects.
Therefore the correct option is C.

Answer:
Errors in the human genetic code, which are called mutations, sometimes lead to the production of abnormal proteins that may cause disease, including autoimmune disease and malignancy.A gene mutation is a permanent alteration in the DNA sequence that makes up a gene, such that the sequence differs from what is found in most people. Mutations range in size; they can affect anywhere from a single DNA building block (base pair) to a large segment of a chromosome that includes multiple genes.

What happened if we add normal saline instead of PBS during beta amylase extraction?
Answer:
hi
Explanation:
Saline is the solution of water and NaCl does not provide the appropriate pH, so enzyme activity is lost, we cannot add saline instead of PBS during beta amylase extraction.
How saline water affects beta amylase extraction?PBS (phosphate buffer solution) is a type of buffer that is suited for beta-amylase activity, which implies that when beta-amylase is extracted using buffer, the enzyme's chemical activity is kept.
When we utilize saline, which is a solution of water and NaCl, the pH of the solution is not acceptable, and the enzymes' chemical activity is destroyed.
As a result, for enzyme/protein extraction, we always employ a buffer solution, which maintains the ph for the proper functioning of an enzyme.
Therefore due to pH conditions enzyme lost activity, and normal saline water can not be used instead of PBS for extraction of beta-amylase.

Answer:A) Patau Syndrome (Trisomy 13) causes intellectual and physical disability, such as underdeveloped eyes, extra fingers/toes, heart defects. Survival beyond the first year is uncommon.
B)
Explanation: Trisomy (or aneuploidy in general) can result when chromosomes to do not separate correctly during mitosis or meiosis. In meiosis, non-separation of a chromosome pair results in a gamete with two copies of the chromosome (and consequently one gamete lacking the chromosome.
At fertilisation the embryonic cell will have three copies of the chromosome (and an embryonic cell with one copy only). These are serious mutations, many of which are non-viable and usually abort spontaneously. Others results in abnormal development and poor survival rates. Only one autosomal trisomy (21) and sex chromosome trisomies (XXX, XXY etc) result in babies that survive into adulthood, albeit with physical and developmental abnormalities (trisomy 21 abd trisomy X). Only one monosomy (XO) is viable.
Other mutations can be less inimical, and may not result in any variation from normal. Mutations in genes coding for proteins or ribosomes may result in potential loss of function. As there are two copies of each gene, the mutated gene is paired with a normal gene and if that is expressed there will be no loss of function.
There are cases where the mutated gene is dominant it will change the phenotype. An example is Marfan Syndrome, an autosomal (chromosome 15) dominant mutation resulting in connective tissue abnormalities and long bones.
An autosomal recessive mutation is not expressed but is carried. If both parents are carriers, the probability of offspring to be doubly recessive and have an altered phenotype is 25%. Cystic fibrosis is an example.
A third possibility is where two alleles are co-dominant. An example of this is sickle cell disease. Consider the three allele pairs SS, Ss and ss.
Those with ss have sickle cell anaemia, a painful and debilitating condition. Those with SS have normal blood cells. Those with Ss have sickle cell trait, which has some mild deficits because a proportion of blood cells are abnormal.
