a. anaerobic metabolism
b. lactic acid metabolism
c. aerobic metabolism
Answers
Answer:
The correct answer is a. anaerobic metabolism.
Explanation:
Anaerobic metabolism refers to a high intensity of exercise in which the absence of oxygen limits performance due to the accumulation of metabolites and the corresponding metabolic and physiological dysregulation.Predominantly anaerobic exercises are characterized by: high intensity and short duration, energy is obtained from immediate sources such as muscle ATP, phosphocreatine (PC) and glucose and does not need oxygen for this. For very explosive or high intensity movements it is necessary to obtain a powerful and fast energy, this is obtained by anaerobic systems. The anaerobic metabolism is able to respond immediately to the energy demands of physical exercise and can provide energy for very high intensity exercises (strength and / or power). But this system has a limited capacity, it is short-lived, so if the exercise continues, either you have to stop due to fatigue or reduce its intensity (the power developed) to a level where energy can be obtained through the aerobic metabolism.

Scenario: You want to determine whether plants communicate with their neighbors in response to stress, so you design an experiment. You have two groups of plants, one that will be exposed to a stressor and another that will not. You apply the stress 3 times a day for 10 days. At day 1 you measure the amount of stress hormone in the plants and then again you measure the amount of stress hormone on day 10.
Answers
Here, the hypothesis is "plants communicate with their neighbors in response to stress", dependent variable is the amount of the stress hormone in the plants, and the independent variable is the exposure to stress (applied 3 times a day for 10 days), standardized variables are plants used, duration of the stressor, amount of stress hormone. The control group is the plant that is not exposed to stressor.
What is the significance of the control group?Here, the control group is the group of plants that are not exposed to stress, and the control groups plants are experimented or tested with the other plants to get the result of the stress hormone on the plants.

What do you think some of the negative consequences of gender socialization could be?
Answers
One negative consequence of gender socialization is the reinforcement of gender stereotypes. Stereotypes are oversimplified and often inaccurate beliefs about groups of people, and they can lead to discrimination and prejudice. Gender stereotypes can limit individual choices and opportunities, as well as contribute to gender-based violence and other forms of inequality.
Another negative consequence of gender socialization is the pressure to conform to traditional gender roles and expectations. This pressure can limit individual expression and creativity, and it can also contribute to mental health issues such as anxiety and depression.
What features developed between Platyhelminthes and Nematodes and the closest previous branch of the tree? They are related to all the other branches, how? What do they have in common with their closest relatives? What's different?
Answers
Answer:
Explanation:
Platyhelminthes and Nematoda are two phyla of animals made up of invertebrate worms. Although both strains are made up of worms, the two types of worms are not closely related. The main difference between Platyhelminthes and Nematoda is that Platyhelminthes is made up of flatworms with a thin, dorso-ventrally flattened body, while Nematoda is made up of a cylindrical body that tapers to fine ends at each end. Tapeworms, Turbellaria, Trematoda, and Monogenea are examples of Platyhelminthes. Secernentea, Enoplea, Chromadoria and Adenophorea are the examples of the nematodes. The flatworm Planaria and the roundworm Caenorhabditis elegans are the best-studied worms in the laboratory.

Biology 3.03 Lab: Dichotomous Key 1. I desperately need help.
Create a dichotomous key that identifies the 10 leaves on the Common Leaves sheet. Look closely at those leaf samples and devise a dichotomous key that helps you identify them. Be sure that your dichotomous key contains only pairs of statements about a single characteristic. For example, a pair of statements might be:
A. leaf margin smooth
B. leaf margin toothed
However, you should avoid pairs of statements that do not address the same characteristic. The following pair, for example, would not be very informative in your key:
A. leaf margin smooth
B. leaf type needle-like
As you develop your key, test it out with the 10 leaves provided on the Common Leaves sheet. When you've developed a key that identifies all 10 leaves, type your statements, “go tos,” and identifications, following the format in the example below. The example is based on this lesson’s dichotomous key for birds.
Once you have completed your dichotomous key, answer the two remaining questions. When you are finished, submit this assignment to your teacher by the due date for full credit.

C
Finches that were able to change their genotype to match the environment were most likely to survive.
D
Finches with traits better suited for survival were able to reproduce and pass these traits to their offspring.
Answers
Natural selection is the evolutive force responsible for changing the frequency of alleles observed in the medium ground finch population. The new trait was spread when mutated animals mated and reproduced. Part A: A) Natural selection. Part B: D) Finches with traits better suited for survival were able to reproduce and pass these traits to their offspring.
What is natural selection?
Natural selection is an evolutive force that selects beneficial alleles and increases their frequency in the population.
Natural selection favors an allele or act against it. It depends on how the allele affects the fitness of individuals.
The phenotype that expresses the best fitness results in higher survival, fertility, and reproductive rates. Aptitude -fitness- must be significant to the natural selection act in its favor.
Adaptation, acchieved by natural selection, is closely related to selective pressures.
Selective pressure is applied by different organisms or conditions that influence the survival rate of a certain phenotype. It influences the probability of a genotype leaving its gametes to the following generations.
In the case of finches, the selective pressure was the drought, that drove finches to suffer a mutation in their beaks size.
Natural selection was responsible for the rapid change in the finches' population beaks size after the drought. The evolutive force modifies the allelic frequencies, increasing the frequency of genetic variants that expressed the larger beak size and declining the frequency of the alleles that expressed smaller beak size.

Answers
Answer:
The correct option is 3. Atoms and molecules are added to dust grain, masses of matter form around dust grain, and masses of matter collide.
Explanation:
Two theories explain how planets get formed. One of them is The gravitational instability, and the other one is the Planetesimal Hypothesis.
The planetesimal hypothesis says that a planet formation is a process in which dust particles and gas collide and get stick together in a process known as coagulation. This makes place to grains production. These grains enhance their sizes up to a point in which they form bodies big enough to be called planetesimals. When planetesimals are formed, they start a gravitative interaction with other planetesimals of different sizes, and by collision, they form bigger planetesimals that accrete the smaller ones and end up forming a proto-planet. Planets and giant planets get formed by accretion of solid planetesimals. The term accretion refers to the solids agglomeration to form bigger objects, such as planets.

The table shown below represents the number of species growing in an area that was logged using clear-cutting 45 years ago in Temagami, Ontario. Data was collected periodically over 45 years.
Describe the changes occurring in vegetation type and species diversity over the 45 years.
What does the pattern of change tell you about what is happening in this area?
Explain how the data supports your conclusion.
Answers
Here is an analysis of the changes in vegetation and species diversity based on the data:
In the first years after logging, the area was dominated by grasses, with 32 species present after 1 year. Shrubs and trees were initially absent. This indicates that grasses rapidly colonized the disturbed area after logging.
Over time, the number of grass species declined as shrubs and trees became established. Shrubs first appeared after 5 years and gradually increased, with 18 species present after 45 years. Trees were absent for the first 15 years but then increased to 24 species after 45 years.
The total number of species showed a steady increase over the 45 years, from 32 species initially to a maximum of 77 species after 45 years. This indicates that species diversity was low immediately following the disturbance but gradually recovered and surpassed the original diversity levels.
The pattern of changes suggests that after the initial disturbance of logging, grasses were the first vegetation to recover and colonize the open area. Then over time, shrubs and trees established and the plant community transitioned from grasses to shrubs to trees. This successional progression from early to later species resulted in an overall increase in species diversity as different types of plants colonized the area.
In summary, the key conclusions supported by the data are:
Grasses rapidly colonized after disturbance while shrubs and trees were initially absentShrubs and trees gradually established over time, replacing some of the grass speciesTotal species diversity increased as different vegetation types colonized, reaching maximum diversity after 45 yearsThe changes indicate a successional progression from early colonizers to later species that resulted in higher diversity.2 cm² enzyme enzyme bolled enzyme 1 1 pH 2 pH 7 pH 8 pH 11 of enzyme was added to test tube A, how much enzyme must added enzyme D

D. Can be composed of a variable number of repeats in different people
Explanation:
Short Tandem Repeats (STRs) are short DNA motifs, i.e., short nucleotide repeat units (generally 2-7 base pairs in size) that may have a different number of repeats among individuals (alleles). Polymorphic STR sequences are very useful genetic markers and therefore they are used for different purposes, e.g., for constructing genome linkage maps, identification of individuals and/or populations, paternity testing, etc. For example, in the USA, the Combined DNA Index System (CODIS) is a databank that stores different DNA profiles based on 13 core STR loci which are used in forensic identity testing.

Answers
The cell membrane's inside is hydrophobic, meaning that water won't cling to it. In order to effectively separate fluid inside the cell from fluid outside the cell, phospholipids form a two-layer cell membrane.
Why do polar molecules repelled by the phospholipid bilayer?Large hydrophilic polar or ionic molecules find it difficult to pass through the phospholipid bilayer. The cell membrane prevents the passage of any size charged atoms or molecules.
What component of the phospholipid bilayer is water-repellent?While the tails (the lipid component) are non-polar, the heads (the phospho part) are polar. The tails, which face the inside of the cell membrane, are "hydrophobic" (fearful of water), whereas the heads, which make up the exterior and inner linings, are "hydrophilic" (lovers of water).
