All of the following are true about thymine dimers EXCEPT: the type of repair that is done to fix them is called nucleotide excision repair they are caused by UV radiation damage that fuses thymines that are next to each other on the same strand individuals with xeroderma pigmentosa (XP) are unable to repair this type of DNA damage, leading to cancer cell development they are caused by UV radiation damage to thymines that are opposite each other on different DNA strands
Answers
Answer:
Option 4, they are caused by UV radiation damage to thymines that are opposite each other on different DNA strands
Explanation:
Thymine dimer is formed on adjacent thymine and hence they lie next to each other on the same strand. They do not lie on strand that are opposite of each other on different DNA strand.
Hence, option 4 is correct

Why is vision considered to be a more effective sense in the terrestrial environment than in the aquatic environment?
Answers
Answer:
Why is vision considered to be a more effective sense in the terrestrial environment than in the aquatic environment?
Mostly its species bias. Our eyes are adapted to be more effective in a terrestrial environment during daylight. But sea creatures have far more impressive eye adaptations to seeing in the water where our eyes are less effective. The most amazing eyes across all species are the eyes of the octopus. In the water eyes don’t need to see color. Wasting valuable space on the retina for color receptors make it hard to see in the low light found in underwater environments. But the octopus’s eyes see color without having any color receptors. They do this by having lenses that act as a prism and separates light into its various colors. The octopus’s brain aligns the image scattered by color by where each color hits the retina. This allows it to see great in low light and also “see” colors. It uses this for camo to change its colors to blend in with its surroundings both to hunt prey and ide from predators. It can change colors instantaneously. The interesting thing about the octopus is it has no central brain. Its entire nervous system can act as individual brains allowing extreme ability to multitask. One of its eight limbs is thinking about what it will do while another is thinking both independently and with communication to the collective nervous system. reaction time of the octopus’s nervous system is unbelievable. We are very slow by comparison probably because a central brain is far less efficient when it comes to processing and reacting to stimuli. Anyway the question is about eyes so I will end my tangent there. The octopus eye system is probably the most advanced eye that exists. They even climb out of the water and demonstrate great visual acuity while out of the water. Our eyes are extremely limited when we are underwater.
Have energy to dissolve metals and other subtances?
Answers
Explanation:
Dissolving metals is a chemical property that takes place when water or strong acids react with metallic objects. Chemical forces pull metal atoms from the object, causing it to break apart and leave the atoms floating freely in solution. Solubility depends on the acids and metals involved. Lead and iron react easily, while platinum and gold are much harder to dissolve.

What cell is this ?
Answers
Answer:
Animal cell
Explanation:
SLO-4.2. Within all tissues in the body, there are stores of undifferentiated cells that can become any specialized type of cell in that tissue for the purpose of growth and healing. Today, Regenerative Medicine is trying to employ these cells to replace tissues that have been destroyed by disease and trauma, such as spinal cord injuries. What are these cells
Answers
Answer:
These cells are stem cells.
Explanation:
Stem cells have not specialized to be in a specific tissue and have a particular function yet. They are the cells that give all the different cell types that our body has. In other words, they can become any cell type that the body needs. We call them pluripotent cells because they have the potential of becoming any specialized cell.
Scientists use stem cells in tissue or organ regeneration due to the pluripotential that they have.

Producers, consumers, and decomposers play important roles in the environment. Are there any organisms that would not fall into one of these categories? Explain your answer.
Answers
Answer:
No, there are no organisms that will not fall into these categories
Explanation:
Living organisms interact with one another in their natural environment in order to ensure that energy needed for their metabolic activities is obtained. To do this, each organism plays different or specific roles. The roles that every organism must fall into are as follows:
- Producers are groups of organisms that have the ability to synthesize their own food using light (photosynthesis) or chemicals (chemosynthesis). Examples are green plants, algae, some bacteria etc.
- Consumers- These are organisms that lack the ability to synthesize their own food and hence depend on other organisms for their energy source. Consumers can either be herbivores (eat plants) or carnivores (eat flesh) etc. Examples are all animals etc.
- Decomposers- These are organism that have the ability to breakdown dead organisms into organic matter, thereby, adding nutrients back to the soil. Examples are fungi, bacteria, earthworm etc.
Based on this explanation above, no organism will not fall into any of these three categories. Some can even occupy two roles.
Which type of selection occurs when a population experiences a shift in diversity toward the larger organisms? o stabilizing selection directional selection disruptive selection adaptive selection
Answers
Answer:
Directional selection
Explanation:
This because directional selection is type selection in which a particular phenotype is choosen and favored among several other phenotypes which cause a shift in diversity of larger population of organisms causing the population to shift in over time in a direction towards the choosen phenotype.
Directional selection
The distribution of population elements along a continuum of homogeneity to heterogeneity with respect to one or more variables is characterized as population diversity. Measures are specified using variance-based interpretations that can be applied to qualitative data.When individuals with qualities on one side of the population's mean survive or reproduce more than those on the other, this is known as directional selection.Directional selection occurs when a population experiences a shift in diversity toward the larger organismsFor more information:

Explanation:
Ribosomes provide the scaffolding on which tRNAs interact with mRNA during translation of an mRNA sequence to a chain of amino acids.
a. True
b. False
Answers
Answer:
a. True
Explanation:
Ribosomes are ribonucleoprotein complexes composed of RNA and proteins, which have two main roles 1-decode the message of the messenger RNA (mRNA) molecule and the formation of peptide bonds in the protein. For this purpose, each triplet of nucleotide bases or 'codon' in the mRNA sequence is used to assemble specific amino acids in the nascent polypeptide chain. Although different, both prokaryotic ribosomes and eukaryotic ribosomes are composed of two subunits: one small subunit that decodes the mRNA into a specific amino acid chain, and one large subunit that forms the peptide bonds in the polypeptide chain. Each ribosomal subunit is in turn composed of ribosomal RNAs and proteins. These ribosomal RNAs act as scaffolds by combining with proteins that assemble into ribosomes (i.e., small and large ribosome subunits).

If a pet has to survive without your care, how would its diet change? Write your ideas on the lines below. Read about how organisms get food and energy in their environment
Answers
Answer:
rather than consuming "pet food" that contains all proper nutrients required your pet would being to scavenge for food wherever they could find it. Survival instincts would kick in and they would eat whatever they could find. Depending on food availability, loss of muscle mass is a possibility.
Explanation:
If my pet is to survive without me, its diet will change. First of all, he will not get food, so how is it possible for a living being to survive without food. It will get skinny and starve to death after a few days.
What is Diet?Diet is defined as the sum of food that is consumed by a person or other organism. The term diet refers to the use of a specific intake of nutrition for health or weight-management reasons. Humans are omnivores so, every culture and every individual has some food preferences or some food taboos.
It is essential for good health and nutrition protects you from many chronic non-communicable diseases like heart disease, diabetes and cancer. Eating a variety of foods and consuming less salt, sugar, and saturated and industrially produced trans-fats are important for a healthy diet.

will All mutations become more common in a population.
Answers
Answer:
False
Explanation:
Mutations are changes in the genetic (nucleotide) sequence of the genome of an organism. According to their effects, mutations can be divided into beneficial, neutral and detrimental for the fitness of the organism, i.e., its ability to survive and reproduce in a given environment. Moreover, mutations can also be classified according to the type of cell that suffers the mutation into 1-somatic mutations that occur in somatic cells and are not inherited, and 2-germinal mutations that occur in germinal cells (i.e., gametes) which can pass to the next generation. In regard to the question above, only those mutations that occur in the germline and are beneficial for the organism (in the environment in which it lives) are expected to become more common in a population.
