Which product is the result of light reactions in photosynthesis? O A. Water B. Glucose O c. Carbon dioxide OD. Oxygen
Answer:
D. Oxygen
Explanation:
Plants absorb carbon dioxide (CO2) and release oxygen for humans and animals to breathe in. Afterward, they'll release CO2 for plants to absorb, which forms a cycle.
Answer:
Oxygen
Explanation:
Both light dependent and light independent reactions in photosynthesis create glucose. But, only light dependent reactions convert carbon dioxide to oxygen.
Light independent: Carbon dioxide + water --> ATP and NADP(Energy/Glucose) and water
Light dependent: Carbon dioxide + water + light --> Glucose(ATP and NADP), water, and oxygen
Which two animals are able to generate internal heat to maintain their body temperature in a coid environment
Parrots and Dogs are able to generate internal heat to maintain their body temperature in a coid environment. Parrots and Dogs are Endotherms. They generate most of the heat they need internally, when it's cold outside.
Does natural selection affect humans? How and why
Answer:
Yes it does affect humans.
Explanation:
Natural selection acts on the phenotype, but evolution is a change in the frequency of alleles in a population over time, a change in genotype. So natural selection acts on phenotype, but it is the connection to genotype that makes it the mechanism of evolution. Many traits vary among different members of a population of humans and animals, from body size to hair color, and those differences are often linked to differences in genes. Natural selection occurs when some of those traits help some individuals survive and reproduce more than others. In scientific terms, these hazards are referred to as selection pressures. They put pressure on us to adapt in order to survive the environment we are in and reproduce. It is selection pressure that drives natural selection "survival of the fittest" and it is how we evolved into the species we are today.

Identify the 2 constructive processes from the list below.
A) A river wears away the land creating a canyon.
B) Over time a mountains top becomes less jagged and more rounded.
C) A volcano erupts and lava flows down its sides.
D) Silt is deposited at the mouth of a river.
Answer:
C, D.
Explanation:
C: The flowing lava creates extra rock. For example, entire islands are formed via this process of volcanos erupting, lava cooling, repeat.
D: Silt from erosion (erosion itself is considered destructive, but the resulting silt can turn into something constructive.) can build up entire mounds or mountains over time.

What are some "topics" to be considered when discussing the California Current
Ecosystem
Answer: Red tide events
Explanation:
Red tide events causing massive fish die-offs, unprecedented sea ice loss, erosion of coastal wetlands, and bleaching of coral reefs not only impact marine ecosystems but also communities, peoples' well-being, local businesses, and more.
These issues impacting ecosystems and people require solutions that consider ecosystems and people. These types of solutions are Ecosystem-Based Management, which considers social, economic, and ecological trade-offs when deciding how to address these issues.
Why do hunters kill young deers instead of the old?
Lactase is an enzyme that many different animals have that helps digest the sugar lactose Why can this enzyme be the same in different species?
0 Lactase is necessary for survival of all organisms
0 All living things share a common code-DNA
0 Lactase is not regulated by external environments.
It is not possible for it to be the same in different species
Answer:
All living things share a common code-DNA
Explanation:
Enzymes are proteinous substances, which like every other proteins are encoded by a genes. In the expression of these genes, a set of codons (three nucleotide base) called GENETIC CODE is used. ONE of the characteristics of this genetic code is that it is NEARLY UNIVERSAL meaning that the same genetic code is used by virtually all known living organism.
According to this question, lactase enzyme, which helps digest lactose sugar in organisms, is the same in different organisms. This is due to the fact that all living things share a common code-DNA e.g AUG codes for methionine in all organisms, hence, when these DNA undergoes expression, it yields the same products in different organisms.

Explanation:
When the Earth's continental crust and ocean crust formed, they were different densities. Why did they differ in density and how did this affect their formation?
A.) The continental crust was thicker and less dense. It rose above sea level, separating land from water.
B.) The continental crust was thicker and more dense. It sunk below sea level, separating land from water.
C.) The continental crust was thinner and less dense. It rose above sea level, separating land from water.
D.) The continental crust was thinner and more dense. It sunk below sea level, separating land from water.
I think it’s B, but I’m not completely sure. Help please!
Answer: A.) The continental crust was thicker and less dense. It rose above sea level, separating land from water.
Explanation:
The Ocean crust is made out of rocks like basalt with a thickness of about four miles. The Continental crust on the other hand is made out of granite and other similar minerals and is between six and 47 miles in thickness which makes it thicker than the Oceanic crust.
With basalt being more dense than granite, the Oceanic crust sank and the Continental crust rose thereby separating land from water.
Answer:
Answer: A.) The continental crust was thicker and less dense. It rose above sea level, separating land from water.

What posture is a dog displaying if she is leaning away from your, body lowered, ears back, tail down, showing whites of her eyes and the corners of her mouth pulled back.
Answer: Fearful and worried posture
Explanation:
Since dogs cannot talk, their body languages are used to interpret whatever emotion or feeling they may be experiencing.
When a dog is afraid, she tries to look small. She lowers her body and and leans away so that her center of gravity is over her hind legs to make a quick retreat easy. She also puts her tail down and ears flattened back to her skull. Her eyes also look rounder than normal and she shows the whites of her eyes (whale eyes).
All these tell that a dog is scared and worried or feeling tense.
Answer:
Defensive Threat Posture
Explanation:
Whale eye (whites of eyes showing)
Tail down or fully tucked
Piloerection
Ears back or flatten against head
Pupils dilated
Corners of mouth pulled back
Body lowered
Body leaning backward
A defensive threat posture indicates a dog is being self-protective. This is seen in a dog who is fearful and would prefer to run away from the situation, but may bite if provoked or cornered. Stress signals were offered in the beginning, however ignored and the dog is showing extreme fear.

How would a bacteria explore a non-coding portion of DNA?
Explanation:
Non-coding DNA sequences are components of an organism's DNA that do not encode protein sequences. Some non-coding DNA is transcribed into functional non-coding RNA molecules (e.g. transfer RNA, ribosomal RNA, and regulatory RNAs). Other functions of non-coding DNA include the transcriptional and translational regulation of protein-coding sequences, scaffold attachment regions, origins of DNA replication, centromeres and telomeres. Its RNA counterpart is non-coding RNA.
The amount of non-coding DNA varies greatly among species. Often, only a small percentage of the genome is responsible for coding proteins, but an increasing percentage is being shown to have regulatory functions. When there is much non-coding DNA, a large proportion appears to have no biological function, as predicted in the 1960s. Since that time, this non-functional portion has controversially been called "junk DNA".[1]
The international Encyclopedia of DNA Elements (ENCODE) project uncovered, by direct biochemical approaches, that at least 80% of human genomic DNA has biochemical activity, which they defined as being transcribed, a definition not shared with most other biologists.[2] Though this was not necessarily unexpected due to previous decades of research discovering many functional non-coding regions,[3][4] some scientists criticized the conclusion for conflating biochemical activity with biological function.[5][6][7][8][9] Estimates for the biologically functional fraction of the human genome based on comparative genomics range between 8 and 15%.[10][11][12] However, others have argued against relying solely on estimates from comparative genomics due to its limited scope.[citation needed] Non-coding DNA has been found to be involved in epigenetic activity and complex networks of genetic interactions and is being explored in evolutionary developmental biology.[4][11][13][14]
1) Eubacteria cells lack a nucleus, and are therefore________
Viewing eubacteria requires a microscope,because they all single celled organisms.another word for single celled is_______
Answer:
The correct answer is - prokaryotic and unicellular.
Explanation:
Eubacteria is known as the true bacteria and belongs to the prokaryotic type of cells which is characterized by no double-membrane organelles or the nucleus. All the genetic material is present in the cytoplasm itself.
These bacteria are single-cell microscopic organisms as they are very minute to see by the naked eyes and required a microscope to study. Another word for the single-cell organisms is unicellular.
