During his trip on the HMS Beagle, Darwin found that ______________.
A plants and animals living in temperate regions were most similar to each other, regardless of the continent on which they were found.
B fossils found on a particular continent were clearly not related to the plants and animals living on that continent today.
C plants and animals were similar on every continent and in every type of region.
D plants and animals living on one continent seemed more closely related to each other, than to plants and animals living in similar regions on other continents.
Answer:
Option D
Plants and animals living on one continent seemed more closely related to each other than to plants and animals living in similar regions on other continents.
Explanation:
From Darwin's discoveries, he noticed that there was a strong relationship between the environment and the characteristics of the living organisms present there. He proposed that the environmental conditions affected the development of certain traits in organisms present there, in their quest for survival and adaptation.
These traits were passed down from parents to offspring, producing a population of organisms with similar character traits found around the same geographical location (continent in this case)

Which of the following objects could be used to model the structure of a DNA molecule?
A. a snowflake
B. a ladder
c. a three-dimensional cube
D. a branching tree
Answer:
Ladder
Explanation:
The structure of the double helix is often described as being like a ladder that has been twisted into a spiral shape. Therefore, option (B) is correct.
What is the structure of DNA?DNA (deoxyribonucleic acid) is a long, linear polymer that is made up of repeating units called nucleotides. Each nucleotide consists of a sugar (deoxyribose), a phosphate group, and one of four nitrogenous bases: adenine (A), guanine (G), cytosine (C), or thymine (T). The sequence of these nitrogenous bases determines the genetic information encoded in DNA.
One of the most common models for the structure of DNA is the "double helix" model, which was proposed by James Watson and Francis Crick in 1953. This model depicts DNA as a double-stranded helix that is held together by hydrogen bonds between the complementary nitrogenous bases A and T, and G and C. The two strands of the helix are antiparallel, meaning that they run in opposite directions. The structure of the double helix is often described as being like a ladder that has been twisted into a spiral shape.

What is the path blood takes through the heart, body and lungs.
Answer:
Blood comes into the right atrium from the body, moves into the right ventricle and is pushed into the pulmonary arteries in the lungs. After picking up oxygen, the blood travels back to the heart through the pulmonary veins into the left atrium, to the left ventricle and out to the body's tissues through the aorta.
Explanation:
Answer:
1) body –> 2) inferior/superior vena cava –> 3) right atrium –> 4) tricuspid valve –> 5) right ventricle –> 6) pulmonary arteries –> 7) lungs –> 8) pulmonary veins –> 9) left atrium –> 10) mitral or bicuspid valve –> 11) left ventricle –> 12) aortic valve –> 13) aorta –> 14) body.

If the PH or the temperate where the enzyme is located changes, the enzyme is very likely to
denature (become inactive/ stop working)
True
False
Answer:
very true
Explanation:
they dont like change:)
Enzymes are proteins that help speed up metabolism, or the chemical reactions in our bodies.
If the PH or the temperate where the enzyme is located changes, the enzyme is very likely to denature is a true statement.
What are enzymes?The enzymes show the best activity at optimum temperature and pH. When there is a change in the temperature, the structure of the enzyme is changed.Any change in the temperature or pH will result in the breaking of the peptides or disulfide bonds. This will disturb the tertiary structure of the enzyme. At the lower temperature, the enzymes get deactivated while, at a higher temperature, it gets denatured.Thus, we can conclude that the correct option is True.

Cellular respiration is essential for the survival of the Euglena. Why?
Please help me.
Answer:
This organism is able to carry out both photosynthesis and cellular respiration. That's why cellular respiration is essential for the survival of the Euglena.
A sequence of chemical processes known as cellular respiration convert glucose into ATP, which can then be used as energy for a variety of bodily functions.
What is cellular respiration?Glycolysis, the citric acid cycle, and oxidative phosphorylation are the three basic processes that take place during cellular respiration. The citric acid cycle happens in the mitochondrial matrix, oxidative phosphorylation happens on the inner mitochondrial membrane, and glycolysis happens in the cytoplasm.
Glucose, ATP, and NAD+ are the initial reactants and ATP and H2O are the end products of cellular respiration. The enzymes phosphofructokinase-1, pyruvate dehydrogenase, and isocitrate dehydrogenase control the rate of cellular respiration.
Disorders that interfere with cellular respiration often impair one or more of the enzymes necessary for it, such as succinyl-CoA synthase or pyruvate kinase.
Therefore, A sequence of chemical processes known as cellular respiration convert glucose into ATP, which can then be used as energy for a variety of bodily functions.

When 2 or more organisms compete for the same resource there can be a variety of outcomes. What would be one of those outcomes?
Answer:
The biology branch deals with the relations between and physical environment of organisms.
Explanation:
The principle of competitive exclusion states that if two species occupy the same niche, they cannot exist together (competing for identical resources). Two species whose niche overlap can evolve to have different niches through natural selection, resulting in the distribution of resources.
In ecology, interspecific competition is a form of competition where individuals from different kinds compete in an ecosystem for the same resources (e.g. food or space)... There may be interspecific competition if people of two separate species share a limited resource within a single area.

a. the long strands of nucleotides are twisted into a double helix.
b. short strands of DNA are contained in chromosomes inside the nucleus of a cell.
c. DNA consists of two strands of nucleotides joined by hydrogen bonds.
d. every DNA nucleotide contains a sugar, a phosphate group, and a nitrogen base.
Answer:
short strands of DNA are contained in chromosomes inside the nucleus of a cell.
Explanation:
DNA is an acronym for deoxyribonucleic acid. It is composed of a sugar, a phosphate group, and a nitrogen base.
DNA consists of two strands of nucleotides joined by hydrogen bonds. This makes DNA appear in a double helical structure.
Long strands of DNA are contained in chromosomes inside the nucleus of a cell. Long strands of DNA in the nucleus are rolled into neat little bundles. Hence the statement; ''short strands of DNA are contained in chromosomes inside the nucleus of a cell'' is false.
