Answer:
A good example happens during the breakdown of food particles.
Explanation:
The chemical energy stored in food is a type of potential energy. Transformation of this energy into kinetic energy happens during chemical reactions that takes place during digestion. A good example of kinetic energy is therefore the breakdown of carbohydrates into carbon dioxide, water and heat.
Which of the following activities were asked about when determining activity level?
a. stretching and flexibility.
b. specific exercises like running, swimming, and biking.
c. moderate household chores.
d. resistance (weight) training.
e. sedentary activities like watching TV and computer use.
f. moderate exercise that causes increased heart and breathing rate.
Answer:
b. and f.
Explanation:
The two main categories of activities that are asked about are specific exercises like running, swimming, and biking. As well as moderate exercise that causes increased heart and breathing rate. These are asked about because they are separate physical activities from an individual's everyday life whether it is done as a hobby or for health reasons. They tend to influence the physical status and are therefore important when determining activity level. Other tasks are usually not included since they are considered normal for survival as everyday tasks.
As per the observation, the correct answers about the determining activity level are options:
b. specific exercises like running, swimming, biking, and f. moderate exercise that causes increased heart and breathing rate.
The primary classes of sports which are requested approximately are unique sporting activities like running, swimming, and biking. As properly a slight workout that reasons expanded coronary heart and respiration rate.
These are requested approximately due to the fact they're separate bodily sports from an individual's regular lifestyles whether or not it's miles executed as an interest or for fitness reasons. They have a tendency to steer the bodily reputation and are consequently critical while figuring out pastime level. Other responsibilities are typically now no longer covered because they're taken into consideration every day for survival as regular responsibilities.
What is the activity level?There are three essential approaches to describing the depth of an activity – vigorous, moderate, and gentle.
Thus it is clear that the following activities were asked about when determining activity levels were b. specific exercises like running, swimming, and biking. f. moderate exercise that causes increased heart and breathing rate.

What do we still need to know in order to determine why the two rock formations have such similar minerals?
Answer and Explanation:
Rock is defined as the collection of one or more minerals. Granite, sedimentary rock, igneous rock, metamorphic rock and limestone are the types of rock. Granite is the most common type of rock. Granite is made up of four minerals such as hornblende, feldspar, quartz and mica. Granite breaks down to form sedimentary rocks. Igneous rock begins as magma. The lava and magma harden to form igneous rock. Metamorphic rocks are made from pressure. Rocks are made of one or more minerals, which are cooled and melted together, cemented together, or heated and squeezed together. The mineral occurs naturally and is made of crystals. The earth’s crust is made of rocks. Most rocks are covered by soil. Soil contains the small pieces of rocks. The two rocks have similar composition but different texture. Rocks are formed in different ways. The rocks can be changed from one form to another.

Reconstruct the phylogeny that most simply and accurately accounts for the distribution of synapomorphies among ingroup species. Given matrices as small and simple as the above example, one can "build" the tree from the bottom up in a series of sketches, adding clades or branches representing groups with the fewest synapomorphies near the base of the tree and those with the most at the tips. Using the unlabeled phylogeny as a starting point, draw the stepwise construction of a fully resolved phylogeny to account for all of the synapomorphies, and include the synapomorphies that identify each clade (the first one, character 2, is included to get you started; this is shared by all members of the ingroup).
Complete question:
1). Determine the character states for the following six characters that are present in species OG, 5, 7, 15, 17, 18. Assign the character state found in the outgroup (OG) as a 0 and the alternative derived state a 1; use only two states per character. Example, stem width: 0 = thin, / = thick 1 (Characters and plant species image in the attached files)
2). Score each taxon using the 0 and 1 notation about and add to this matrix (Matrix in the attached files)

NOTE: You will find the complete activity in the attached files.
The principle of maximum parsimony or maximum simplicity states that among all possible trees within a group of species, the most probable is the one that requires us to postulate the least number of evolutionary changes. So, to reconstruct a phylogeny we need to choose the tree that requires the less number of changes. To determine the character states for all the six characters, we assigned the number cero to all the characters expressed in the out-group. Thin steam, blunt leaf, narrow flower base, upward flower orientation, yellow petals, and rounded-seeds are all cero states. The other characters are 1.The above information of character state was used to fill in the matrix, specifying which character state belongs to each species according to their traits. The matrix was useful to reconstruct the phylogeny, to identify the autapomorphic trait, and to visualize all the clades.What is the function of the sepal?

c. a system that uses only intracellular chemicals to destroy invading bacteria
d. a system that enhances the destruction of bacteria through the activation of mast cells, lymphocytes, and phagocytes
Answer:
d. a system that enhances the destruction of bacteria through the activation of mast cells, lymphocytes, and phagocytes
Explanation:
Mast cells are white blood cells (i.e., lymphocytes) that form part of the immune system. These cells form part of the first line of defense against pathogenic organisms. Some of the most important phagocytic cells that function to protect the body by ingesting pathogenic agents (e.g., harmful bacteria) include mast cells, monocytes, neutrophils, macrophages and dendritic cells. In this regard, it is important to highlight that mast cells are similar to basophil granulocytes (another type of lymphocyte), and they are derived from hematopoietic stem cells.
Determine the proportion of offspring phenotypes that would result when two merle dogs mate, if one dog is true-breeding for the long-coat trait and the other dog is true-breeding for the short-coat trait. ResetHelp
Answer:
100% long-coat
Explanation:
Assuming that the long-coat trait is represented by L allele and the short-coat trait by l allele.
True-breeding long-coat dog would have the genotype LL while true-breeding short-coat would have the genotype ll.
Assuming that the long-coat trait is dominant over the short-coat trait.
LL x ll
Ll Ll Ll Ll
All the offspring would have Ll genotype and would appear with long-coat phenotypically. Hence, the proportion of offspring phenotypes is 100% long coat.

Answer:
Mitochondria and chloroplasts have their own DNA
Mitochondria and chloroplasts are surrounded by two membranes
Mitochondria are about the same size as most bacteria
Explanation:
The endosymbiotic theory, also known as symbiogenesis, is a theory that explains how eukaryotic organisms have been formed from prokaryotic cells. This theory holds that eukaryotic organisms originated from prokaryotic organisms that engulfed another prokaryotic cell, creating thus an organism with multiple membranes. In consequence, eukaryotic organelles, including mitochondria and chloroplasts, would have evolved from these prokaryotic endosymbionts. Moreover, both mitochondria and chloroplasts contain their own genes which are localized in a circular chromosome, thereby supporting an endosymbiotic origin of both organelles. Finally, bacterial cells have 1 to 10 microns in length, while mitochondria have a similar size, thereby also supporting an endosymbiotic origin of this organelle.

B)The financial costs for the farmer would be lowered since MORE crops would be lost to pests.
C) The farmer may be held responsible for increasing chemical pollution.
D) The farmer's expenses for pest control would increase due to an increase in bee population.
Answer:
A) The financial costs for the farmer would be lowered since LESS crops would be lost to pests.
Explanation:
Planting of variety with a resistance strain to pest is one of the gene modification that occurs in plants, this has greatly help farmers improve on productivity, reducing the amount of money spent on controlling insect pest invasion on their farm.
Because the crop is resistant to pest no extra cost of purchasing chemicals to control pest on the farm and the number of damage to crop will be reduce in turn reducing the amount of plant lost to pest invasion this will lower the financial cost of the farmer and also an increase productivity.
The trait for tall pea plants is (T) and the trait for short pea plants is (t). The trait for smooth pea plants is (R) and the trait for wrinkled is (r).Two plants are crossed producing a F1 generation of plants with 612 tall and smooth pea plants and 188 short and wrinkled pea plants.What would be the most likely genotype of the parental generation?
Answer:
P generation = TtRr × TtRr i.e both parents were heterozygote for both traits
Explanation:
This question involves two genes encoding the height and texture in pea plants respectively. The alleles for tall and smooth pea traits are dominant over the alelles for short and wrinkled traits.
According to this question, two plants are crossed to produce F1 offsprings as follows: 612 tall and smooth pea plants and 188 short and wrinkled pea plants.
First, we turn this derived number of offsprings into ratio by dividing by the smallest number (188)
612/188 : 188/188
3.25 : 1
Approximately; we can say this is 3 (tall and smooth) : 1 (short and wrinkled)
Based on this ratio, which was got by Mendel for his F1 offsprings when he crossed pea plants, the parental generation has a heterozygous genotype (TtRr).
The primitive streak eventually becomes what system?
Answer:

In pea plants purple flowers are dominant to white flowers.
If two white flowered plants are cross, what percentage of their
offspring will be white flowered?
Answer:
100%
Explanation:
This question involves a single gene coding for flower color in pea plants. The allele for purple flowers (P) are dominant to white flowers (p). This means that purple color will be expressed in a heterozygous state.
According to this question, If two white flowered plants are cross i.e. pp × pp, the following gametes will be produced by each of the parent: p and p. Using these gametes in a punnet square (see attached image), ALL (100%) of the offsprings will be white colored (pp).
Therefore, 100% of the offsprings will be white flowered.
