Answer:

The human heart is a pump. It pumps blood around the body at different speeds and at different pressures according go the body's needs. It can do this because the wall of the heart is made from cardiac muscle. Blood is moved through the heart by a series of contractions and relaxations of cardiac muscle in the walls of the four chambers.

Answer:

Translation is the second part of the central dogma of molecular biology: RNA → Protein. It is the process in which the genetic code in mRNA is read to make a protein. Translation is illustrated in the diagram below. After mRNA leaves the nucleus, it moves to a ribosome, which consists of rRNA and proteins.

Explanation:

Within the ribosome, the rRNA molecules direct the catalytic steps of protein synthesis — the stitching together of amino acids to make a protein molecule. In fact, rRNA is sometimes called a ribozyme or catalytic RNA to reflect this function.

Relation between variables are the different born percentages in sea turtles.

What percentage of sea turtles are female?

Green sea turtles from cooler southern nesting strands were about 65 to 69 percent lady, testing showed. Sea turtles from warmer northern strands leaned indeed more heavily womanish, with86.8 percent of adult turtles,99.8 percent of sub-adult turtles, and99.1 percent of juvenile turtles turning out to be womanish.

How long does it take for a sea turtle to incubate?

The incubation time for utmost species is 45 to 70 days. exploration indicates that the coitus of an embryo is dependent on the temperature of the nest. Lower nest temperatures produce further males; advanced temperatures produce further ladies. For green ocean turtles, a nest temperature of 28 °C(82 °F) or below produces substantially males.

Answer: The organism will not produce the protein coded by the gene.

Explanation:

The effect that will the mutation have on the organism is the organism will not produce the protein coded by the gene. Thus, the correct option for this question is B.

A Mutation may be defined as the sudden, stable, and inheritable changes in the genetic material of organisms. The organism which undergoes mutation is known as a mutant. The agents of mutation are known as mutagens.

The Mutation leads to alterations in the genomic sequences of an organism. Due to this, the proteins formed are different compared to normal. The function of the previous protein is blocked and a new function is visualized.

So, if an organism has a mutation in a gene that blocks its function, the organism will definitely not be able to the protein coded by that gene.

Therefore, the organism will not produce the protein coded by the gene is the effect that will the mutation have on the organism. Thus, the correct option for this question is B.

Answer:

It depends on the light for its growth.

Explanation:

The amount of light available to the Chlorella culture might affect the growth dynamics of the algae because Chlorella is just like plant that prepare their own food with the presence of light. If there is more amount of light received by the Chlorella algae, it prepare more food and more growth occurs while on the other hand, if there is less amount of light available to Chlorella algae so it produce less amount of food and less growth will occur.

Answer:

The correct answer s - by the photosynthesis process.

Explanation:

Plants use the sunlight to convert the atmospheric carbon dioxide and water to oxygen and glucose for their food and energy, this process is called as photosynthesis. In This process, glucose is formed that is linked together to form the storage carbohydrate form, starch, that can use by plants later and store in the different parts of the plants.

In plants like potato and sweet potato or the plants that has tuber or grains, store the starch in their tuber or grains by transporting the starch to the these parts.

The types of isomers present in Pentane with molecular formula C5H12 are Structural isomers, option B.

Structural isomers are isomers in which the atoms are completely different in order but have the same molecular formulas. Structural isomerism occurs when molecules have the same molecular formula but a different structural formula.

Different types of structural isomerism include chain isomerism, position isomerism, and functional group isomerism. C5H12 exists as three chain isomers, one -CH3 groups and two -CH3 groups. Because more branched isomers have weaker Van der Waals forces and thus lower boiling points, chain isomers have similar chemical properties but different physical properties.

Answer:

A monophyletic group must include all species that are descended from a common ancestor, and cannot include any species that are not descended from that common ancestor. Modern evolutionary classification uses a method called cladistic analysis to determine how clades are related to one another. Evolutionary taxonomy, evolutionary systematics or Darwinian classification is a branch of biological classification that seeks to classify organisms using a combination of phylogenetic relationship (shared descent), progenitor-descendant relationship (serial descent), and degree of evolutionary change.

Explanation:

The goal of phylogenetic systematics, or evolutionary classification, is to group species into larger categories that reflect lines of evolutionary descent, rather than overall similarities and differences.

Answer:

C. Spore formation

Explanation:

Option C above is the correct answer.

Spore formation is actually a method of asexual reproduction. Fungi actually reproduce asexually via spore formation. Some examples of organisms that reproduce via spore formation are Rhizopus, mushroom, mucor, etc.

The spores are usually stored in sacs which are known as sporangia. When there is a bursting of the sac, spores that are single-celled, thick and thin walled are obtained/formed. The spores are usually resistant to environmental conditions.

Darwin had seen these birds on a visit in the 1830s to the Galápagos Islands, a collection of islands in the Pacific Ocean to the west of South America.

Artificial selection is the process of identifying desirable qualities in plants and animals and then taking action to strengthen and pass those traits on to succeeding generations.

Artificial selection operates in a similar manner to natural selection, with the exception that in natural selection, these judgments are made by nature without human intervention.

The physical characteristics and behaviors of many kinds of birds known as finches were highlighted by British naturalist and biologist Charles Darwin in his 1859 book On the Origin of kinds, which outlined the evidence for his hypothesis of evolution by natural selection.

Answer: B.  Modern bird species share many genetic similarities.

Explanation:

When organisms are said to have a common ancestor, it means that they share many genetic similarities but are not identical due to evolution and cross-breeding. For instance, siblings may have the same parents but they will not be genetically identical even though they have a lot of similar traits owning to their parents have different traits.

The same is true for birds. They share the genetic characteristics of their common ancestor but as time went on and evolution took place, they changed in some ways and so are no longer genetically identical.

Answer:

C wind erosion is most responsible for the formation of sand dunes.

Explanation:

Sand dunes are formed when wind blows loose sand from a beach, desert, or other location, and deposits it in a new location. The sand is then shaped by the wind into dunes, which can vary in size and shape depending on the strength and direction of the wind. Water erosion, volcanism, and glaciation can all also contribute to the formation of sand dunes to some extent, but wind erosion is typically the primary process responsible for their formation.
