Explicitly explain how a living organism obtains energy after eating.
Answer:
Explanation:
Tiny bits of the food you ate break down into a simple sugar called glucose. In your cells, energy from the sugar is released when oxygen and glucose combine in a reaction. The reaction produces water, carbon dioxide, and energy in the form of ATP. This chemical process is happening all the time in your cells.
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.

55.7 moles of PCl5 will decompose to produce how many moles of PCl3 and Cl2 combined ?Enter your answer correct to 1 decimal place
Answer:
55.7 moles of PCl₃ and 55.7 moles of Cl₂
Explanation:
The balanced chemical equation for the reaction in which phosphorus pentachloride (PCl₅) is decomposed in phosphorus trichloride gas (PCl₃) and chloride gas (Cl₂) is the following:
PCl₅(g) → PCl₃(g) + Cl₂(g)
According to the stoichiometric coefficients, 1 mol of PCl₅ produces 1 mol of PCl₃ and 1 mol of Cl₂. So, the stoichiometric ratios reactant/product are: 1 mol PCl₃/1 mol PCl₅ and 1 mol Cl₂/1 mol PCl₅. Thus, we multiply the stoichiometric ratios by the number of moles of reactant:
1 mol PCl₃/1 mol PCl₅ x 55.7 mol PCl₅ = 55.7 mol PCl₃
1 mol Cl₂/1 mol PCl₅ x 55.7 mol PCl₅ = 55.7 mol Cl₂
Therefore, 55.7 moles of PCl₃ and 55.7 moles of Cl₂ are obtained from the decomposition of 55.7 moles of PCl₅.

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.

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.

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.
Which is a compound that is only found in the cells of autotrophs that perform photosynthesis to enable these organisms to create their own food?
Answer: In photosynthesis, autotrophs use energy from the sun to convert water from the soil and carbon dioxide from the air into a nutrient called glucose. Glucose is a type of sugar. The glucose gives plants energy. Plants also use glucose to make cellulose, a substance they use to grow and build cell walls.
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).

b. a system that inhibits the production of antibodies and histamine, resulting in bacterial death
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.
