what is most likely the cause of the increase in carbon dioxide in our enviorment
Answer:
On Earth, human activities are changing the natural greenhouse. Over the last century the burning of fossil fuels like coal and oil has increased the concentration of atmospheric carbon dioxide (CO2). This happens because the coal or oil burning process combines carbon with oxygen in the air to make CO2.
Answer: Carbon dioxide concentrations are rising mostly because of the fossil fuels that people are burning for energy. ... From 1850 to 2018, 440 ± 20 Pg C (1 Pg C = 10¹⁵ g C) were emitted as CO₂ from fossil fuel burning (Friedlingstein et al. 2019).

A rugged mountain terrain would have a high rate of speciation.
This is because the mountain would prevent organisms from interacting which of course means the gene flow stops altogether.

Most plants have what type of photoperiodism?
short-day plants, long-day plants, and day-neutral plants.
Flowering is the most well-studied manifestation of photoperiodism in plants, additional reactions to day length include bud dormancy and bulb or tuber initiation.
What is photoperiodism?Long-day vegetation Long-day plants (LDP) and short-day plants are the two terms used to describe plants that require longer exposure to light. Short-day plants (SDP) or Day Neutral Plants are those that require less exposure to light.
Positive and negative phototropism are the two varieties. Positive phototropism is the growth in the direction of a light source, whereas negative phototropism is the growth in the opposite direction.
Therefore, negative phototropism is a characteristic of plant roots that arise from the necessity for them to stoke deeper roots for the plant's stability, water, and nutrients.

What common tool does this shape remind you of ?
How many strands do you see?
Answer:
There are 2 strands. The shape if of a double helix, but it reminds me of a twisted ladder.
Explanation:
Hope this helps!
DNA (Deoxyribonucleic Acid) is a molecule that contains the genetic instructions for all known living things' development, operation, growth, and reproduction. Two strands that are twisted together to create a double helix make up the DNA molecule.
What are the two strands of DNA composed of ?The two strands of DNA are composed of nucleotides, which are the substance that gives DNA its structure. A sugar molecule, a phosphate group, and a nitrogenous base make up each nucleotide. Adenine (A), thymine (T), cytosine (C), and guanine (G) are the nitrogenous bases found in DNA.
In DNA, the nitrogenous bases form hydrogen bonds that hold the two strands together. Both adenine (A) and thymine (T) couple naturally with cytosine (C) and guanine (G), respectively. Complementary base pairing is the name given to this base pairing.
For DNA to serve as a carrier of genetic information, its double helix shape is necessary. The genetic code, which contains instructions for how living things develop, grow, and operate, is made up of the nucleotide sequence along the DNA strands.
The mechanism through which DNA duplicates itself, including the two strands of DNA, is also very important. The two DNA strands split apart during DNA replication, and each strand acts as a template for the creation of a new complimentary strand. This procedure guarantees that the genetic material present in the original cell is replicated exactly in each subsequent cell.

The secondary structure of DNA is often B-DNA, which is a double helix that contains a minor groove and a major groove. When dying DNA molecules for DNA laboratory techniques, there are two general types of dyes that specifically bind to DNA to make it fluorescent. One type of dye, such as ethidium bromide, intercalates in between bases inside the DNA, and is only fluorescent when it is intercalated into DNA. Another type of dye rests in the major or minor groove of DNA, such as SYBR Green, and is only fluorescent when it is bound in the groove of DNA. Intercalating dyes are considered to be more carcinogenic than groove-binding DNA dyes if they are absorbed through the skin of the researcher. Which of the following options is the most reasonable explanation for this?
Choose one:
A. The intercalated dyes will lead to increased mutations upon DNA replication since they are inserted into the bases that are used as a template for DNA replication.
B. The intercalated dyes attract more carcinogens in the cell to the DNA than the groove-binding dyes.
C. The groove-binding dyes increase the chance of mutation when DNA is being replicated because the sugar phosphate backbone is used as a template during DNA replication.
D. The intercalated dyes emit more UV light, causing more damage to the DNA than the groove-binding dyes.
The intercalated dyes will lead to increased mutations upon DNA replication since they are inserted into the bases that are used as a template for DNA replication (Option A). It is a mutagenic agent.
Mutations and intercalant agentsA mutation is any alteration in the nucleotide DNA sequence of the genome of an organism.
An intercalant agent is any chemical substance (mutagenic agent) that can insert between successive nucleotides' DNA bases.
Ethidium bromide is a well know intercalant agent used to observe DNA under UV light.

If a cell was producing too much energy, which component would step in to hold the
energy until it was needed?
rough endoplasmic reticulum
vesicles
lysosomes
mitochondria
Explanation:
Mitochondria is the answer
The component that would step in to hold excess energy until it's needed within a cell is the mitochondria.
The mitochondria are the cellular factories that turn food into adenosine triphosphate (ATP) through cellular respiration. A cell may store extra ATP within the mitochondria if it is making more energy than it needs right now. When the cell's need for energy rises, this stored energy can be released.
This mechanism makes sure that the cell effectively manages its energy resources and maintains energy balance. The primary role of other cellular components such vesicles, rough endoplasmic reticulum, and lysosomes is not in the storage of extra energy but rather in transport, protein synthesis, and waste disposal.
