Answers
Answer:
The color of light determines how effective chlorophyll pigment will be at absorbing light.
Explanation:
Photosynthesis is a metabolic process that requires light, which is an electromagnetic radiation. Light on the electromagnetic spectrum is determined by wavelength. Each region/color of light occurs at a specific wavelength.
Hence, chlorophyll pigment, which is the major photosynthetic pigment effectively absorbs blue and red light in the visible light region of the electromagnetic spectrum. Hence, the rate of photosynthesis will be affected negatively if the color of light is not the one stated above.

Mutation is a sudden change in the genome of an organism that is heritable.
Mutation occur due to a spontaneous change in the sequence of a gene, it can occur during DNA (deoxyribonucliec acid) replication, mitosis, meiosis. Some mutation are beneficial, some are detrimental while some could be deleterious. Mutation is a rare occurrence usually one in several hundreds or thousand
The unique traits that was reveal in the bird is due to mutation, it is beneficial because it kept it away from predation it is a rare case.

What is the correct "height" or "size" for a piece of oils rigs to become a candidate for "rigs to reef." Remember, oil rigs can be cut into different sizes or parts.
Answers
Answer and Explanation:
An oil rig is a type of piston ring which is situated in the ring grooves. The oil ring is commonly used on small engines to wipe excess oil from the wall of the cylinder during the piston's movement. Through the opening of rings, excess oil returned to the oil reservoir. These rings are not used on the two-stroke cycle engines. These rings are one-piece or two-piece. An oil ring seals the combustion chamber through inherent pressure and controlling the consumption of oil. The inherent pressure of the oil ring is very high on the piston. These rings use an expander, high-pressure unit and inherent pressure. The oil rings are also used to spread the oil around the liner surface. These rings can be cut into various sizes. An oil ring has an axial.

Transposable elements can induce mutations by all of the following mechanisms EXCEPT: disrupting a gene when inserted into it. facilitating recombination between transposons, producing chromosomal mutations. producing double-stranded breaks during excision, leading to chromosomal mutations. Activating genes with their own promoter, dysregulating them.
Answers
Answer:
Activating genes with their own promoter, dysregulating them.
Explanation:
Transposable Elements (TEs), also known as transposons, mobile elements or jumping genes, are genetic sequences able to move within a host genome by a mechanism called 'transposition'. As a result of their transposition, TEs may cause diverse genetic alterations and disrupt host gene expression at the integration site. Some of the most common deleterious effects induced by TE transposition include, among others, insertional mutagenesis, duplicated sequences, chromosome translocations, etc. Moreover, although it has been shown that some types of TEs contain transcription factor binding sites (as well as cis-regulatory motifs), they don't have promoter sequences that activate host gene expression upon TE transposition.

Answers
Answer:
system
Explanation:
An example of an organ system is the brain, spinal cord, and nerves working together.
A system is a level of organization in living organisms in which body organs work together to perform similar functions. The organ system represents the highest level of body organization as opposed to organ, tissue, and cell level of organization.
The cell is the smallest unit of organization of the body of living organisms. At the tissue level, cells aggregate together to perform similar functions while at the organ level, similar tissues come together to perform somewhat similar roles in the body of organisms.
The brain, spinal cord, and nerves each represent an organ. When these work together in the body of organisms, the level of organization is described as organ systems or simply systems.

Which element has the least neutrons in the nucleus?
Aluminum
Nitrogen
Helium
Fluorine
Answers
Answer:heh
Explanation:
Aluminium , mass no = no of proton + neutron = 27
atomic no = no of proton = 13
no of neutron = 27 - 13 = 14
Nitrogen , mass no = no of proton + neutron = 14
atomic no = no of proton = 7
no of neutron = 14 - 7 = 7
Helium , mass no = no of proton + neutron = 4
atomic no = no of proton = 2
no of neutron = 4 - 2= 2
fluorine , mass no = no of proton + neutron = 19
atomic no = no of proton = 9
no of neutron = 19-9 = 10

the diagram shows a bacterium. Which labels best complete the diagram
Answers
Answer:
X - Flagellum, Y - Bacterial DNA, Z - Cytoplasm
Explanation:
A bacterium is a living thing that are majorly known for causing diseases but are important for human life.
A bacterium is also consist of several organelles such as cell wall, cytoplasm, flagellum, bacterial DNA, cytoplasm, ribosomes and others.
The diagram shows three main organelles that are X - Flagellum, Y - Bacterial DNA, Z - Cytoplasm. Flagella functions for the locomotion of the bacteria, bacterial DNA is a genetic material of the bacteria, and cytoplasm is a gel-like matrix composed of enzymes, water, nutrients and other waste material.
Hence, the correct answer is "X - Flagellum, Y - Bacterial DNA, Z - Cytoplasm".

Compare the reactants and products in the chemical equations below. Which statement best describes the relation between matter and energy?
Answers
Answer and Explanation:
Chemical reactions are very complex processes which include the collision of molecules. During the chemical reactions, bonds between the breakdown of the atom and transformed in new ways. The chemical compounds that react together during the chemical reactions are called reactants, shown on the left side of the equation. They are broken down during the reaction and used as the reaction progresses. The chemical compounds that are formed from the rearrangement and breakdown of the reactants are called products. The products are shown on the right side of the chemical equation. As compare to the reactants, the products are more stable molecules. For example, in the reaction between H2SO4 and Zn, these two chemicals are the reactants, while ZnSO4 and H2 are the chemical reaction products.
Zn + H2SO4 ZnSO4 + H2
(Reactants) (Products)
The matter is a material that everything is made of matter. A property that matter has is known as energy. The same quantity of matter can have a diverse quantity of energy. Both energy and matter are identical. For example, if we add some energy into an ice cube, it will turn into liquid. After that, if we add more energy, liquid will turns into steam.
The incidence of V. vulnificus infections is increasing, especially in northern parts of the United States, compared to 20 years ago. Can you think of any reason why this might be happening?
Answers
Answer:
The effects of climate change may be associated with the increased incidence of V. vulnificus infection
Explanation:
Vibrio vulnificus is a harmful bacterium that causes a serious disease due to eating contaminated seafood, which is the main cause of seafood-related deaths in the USA. V. vulnificus is naturally present in the flora of coastal waters around the world and this bacterium has been isolated from a variety of seafood (e.g.., fish, oysters, shrimp, etc). Epidemiologic studies have shown that the incidence of V. vulnificus infection has increased dramatically since 1996. During this same period, climate change has been responsible for the increase in salinity and temperature of the coastal waters (i.e., the natural habitat of this bacterium). In consequence, it is reasonable to suppose that the change in climatic conditions may be associated with the increased incidence of V. vulnificus infection.
