1. Which statement is NOT true regarding the above picture?
A. Cave fish live in the dark, and therefore no longer needed the adaptational advantage of needing eyes
B. It is not possible that these two fish came from a common ancestor.
C. Cave fish developed different adaptations from minnows because of their surrounding environment, like sensitivity to vibrations.
D. Minnows would not be well adapted for extremely dark environments.
2. What type of evidence of evolution does the above picture represent, when you notice the presence and lack of eyes in the minnow & cave fish?
A. Eyes must be a Homologous structure
B. Eyes must be an analogous structure
C. Eyes must represent biochemical evidence
D. Eyes must be a vestigial structure
Answers
ANSWER
number 1. B
number 2. A
im not 100% sure so please think about it before answering.
The presence and lack of eyes in the minnow & cave fish shows that eyes must be a Homologous structure.
Evolution is the stepwise process by which contemporary organisms emerged from earlier ancestors. We must note that organisms that evolved from the same ancestor must share some structural and functional similarities. Hence, it is not possible that these two fish came from a common ancestor.
A homologous structure is a structure that is present in two species that come from a common ancestor. Hence, the presence and lack of eyes in the minnow & cave fish shows that eyes must be a Homologous structure.

3. Which feature is commonly formed
at a plate boundary where oceanic
crust converges with continental crust?
(1) a mid ocean ridge (2) an ocean trench (3) a transform fault (4) new oceanic crust
Answers
Answer:
2) an ocean trench
Explanation:
Ocean trench is a commonly formed at a plate boundary where oceanic crust converges with continental crust.
What is Ocean Trench?Long, narrow depressions on the seafloor are known as ocean trenches. These chasms are among the deepest natural places on Earth and the deepest portions of the ocean.
Every ocean basin on the planet has ocean trenches, but the deepest ones encircle the Pacific Ocean as part of the so-called "Ring of Fire," which is also home to active volcanoes and earthquake-prone regions. Tectonic activity, which refers to the movement of the Earth's lithosphere, is what causes ocean trenches.
Ocean trenches in particular are a characteristic of convergent plate borders, which occur where two or more tectonic plates collide. In a process known as subduction, dense lithosphere melts or slides beneath less dense lithosphere along numerous convergent plate borders, forming a trench.
Therefore, Ocean trench is a commonly formed at a plate boundary where oceanic crust converges with continental crust.

Answers
Answer:
Above
Explanation:
The anthers are always above the stigma.
Anthers in this flower located always above the stigma are the anthers, the primary reproductive component of the flower, anthers are where male gametes are dispersed.
What are the anthers in flowers?The pistil refers to all of the female components. The stigma, which is a sticky surface open to pollen, is found at the top of the pistil.
A pollen-containing unit is another name for it, the angiosperms' stamens contain it. A filament or stalk, which resembles a thread, supports the object.
Therefore, anthers are where male gametes are dispersed. The top anther and the stalk or filament that supports it are what are known as the masculine components of the flower, or stamens.

Answers
Answer:
1) Light energy and chemical energy should be switched
3) Plants that contain chlorophyll should not be included
5) Animals and plants should be switch
Explanation:
Photosynthesis is a biological process through which green plants make their own food in the presence of sunlight. So, photosynthesis is a process in which Light energy is converted to chemical energy.
Plants carrying chlorophyll should not be included as their primary source is light, carbon dioxide and water.
During photosynthesis, plants make oxygen and releases it into atmosphere which is further utilized by animals or humans for metabolic activities so, photosynthesis allows the flow of energy from plants to animals.

what surfaces or objects on earth would reflect infrared light well?
Answers
Answer:
Infrared, sometimes called infrared light, is electromagnetic radiation with wavelengths longer than those of visible light. It is therefore invisible to the human eye.
Aside from water vapor, bodies of water on the surface of the Earth also absorb IR wavelengths well. Glass, wood, brick, stone, asphalt and paper all absorb IR radiation. While regular silver-backed mirrors reflect visible light waves, allowing you to see your reflection, they absorb infrared radiation.

A. Describe the role of the promoter in eukaryotic gene expression. Explain how a negative regulatory molecule could inhibit transcription at the promoter.
B. Identify TWO events that occur during RNA processing. Explain how RNA splicing increases the variation of mRNA molecules.
C. Describe the role of miRNA in gene expression.
Answers
Answer:
Explanation:
A. The role of promoter in eukariotic gene expression is It is to bind transcription factors that regulate transcription initiation. This molecule is so important because control the binding of RNA polymerase to DNA. The promoter region may be short or very long; the longer the promoter is, the more protein binding space is available. A negative regulatory molecule has the possibilty to inhibit transcription at the promoter because these molecules block the binding of RNA polymerase to the promoter region, thus not allowing the initiation of transcription, in some particular cases, the negative regulator binds to the lac repressor and will bind to the promoter in the same site where RNA polymerase would bind to.
B. Two process that occur during RNA processing are RNA splicing and 5′ capping, 3′. RNA splicing is a procces known for removing the introns from the pre-RNA and stuck back together the restant parts, exons. This process has as a goal form a mature mRNA that does not contain the intron sequences. RNA splicing has effect on variation of mRNA molecules because through a process called alternative splicing more than one mRNA can be made from the same gene.
C. Even though they are not quite the same thing miRNA and negative regulatory molecules have the same role, which is inhibit the translation and silence genes. They regulate gene expression by binding to the 3'-UTR of their target mRNAs and destabilizing the mRNA and translational silencing, repressing protein production. Even so, under specific circumstances, miRNA can activate translation or regulate transcription.

The majority of DNA is found in the cell nucleus (where it is referred to as nuclear DNA), but a minor portion is also present in the mitochondria, where it is referred to as mitochondrial DNA. Mitochondria are organelles in cells that transform food energy into a form that cells can utilize.
What is DNA composed of?Nucleotides are the chemical units that make up DNA. Three components make up these building blocks: a phosphate group, a sugar group, and one of four different nitrogen bases.
Chains of nucleotides with alternating phosphate and sugar groups are joined to form a strand of DNA.
A single molecule of deoxyribonucleic acid and a protein make up each chromosome (DNA).
DNA and proteins arranged into genes make up a chromosome. 23 pairs of chromosomes are typically present in each cell.
Therefore, DNA is found inside nucleus of every living cell!
