Answer: Yes

Explanation: Monocots produce one cotyledon, while dicots produce two. Because seeds are reproductive structures and thus important to a species' survival, plants have evolved many mechanisms to ensure their survival. One such mechanism is seed dormancy. Dormancy comes in two forms: seed coat dormancy and embryo dormancy

Answer:Plants that reproduce by seeds. Seed plants have special structures on them where male and female cells join together through a process called fertilisation. After fertilisation, a tiny plant called an embryo is formed inside a seed.

Answer:

Classification of Living Things. All living organisms are classified into groups based on very basic, shared characteristics. Organisms within each group are then further divided into smaller groups. These smaller groups are based on more detailed similarities within each larger group.

Kingdoms

The much more  basic classification of living things is kingdoms. Currently there are five kingdoms. Living things are placed into certain kingdoms based on how they are obtain their food, the types of cells that make up their body, and the number of cells they contain.

Phylum

The phylum is the second level following kingdom in the classification of living things. It is an attempt to find some kind of physical similarities among organisms within a kingdom. These physical similarities suggest that there is a common ancestry among those organisms in a particular phylum.Classes

Classes are way to further divide organisms of a phylum. As you could probably guess, organisms of a class have even more in common than those in an entire phylum. Humans belong to the Mammal Class because we drink milk as a baby.

The two pieces of evidence that support the theory of the expanding universe are the red shift of light from distant stars and the existence of cosmic background radiation.

The correct answer is option B.

1. Red shift of light from distant stars: The observation of redshift in the light coming from distant galaxies provides evidence for the expansion of the universe. Redshift occurs when the light waves from an object moving away from an observer are stretched, causing a shift towards longer wavelengths. This phenomenon is consistent with the Doppler effect, where the wavelength of light appears to stretch as the source moves away. The redshift of light from distant stars indicates that galaxies are moving away from us and from each other, supporting the idea that the universe is expanding.

2. Existence of cosmic background radiation: The discovery of cosmic background radiation further supports the theory of the expanding universe. Cosmic background radiation is a faint, uniform microwave radiation that permeates the entire universe. It is believed to be residual radiation from the Big Bang, the initial event that is thought to have initiated the expansion of the universe. The presence of cosmic background radiation provides strong evidence for the hot, dense early stages of the universe and its subsequent expansion.

When X fires 10 times and Y fires 10 times, the result will be a subthreshold summation.

Subthreshold summation happens when two or more presynaptic inputs that are sub-threshold (i.e., they cannot create an action potential) combine their effects on the postsynaptic neuron.

Here, the postsynaptic neuron has an RMP of -70mV and a typical threshold of -55mV. When neuron X is stimulated, it depolarizes by 0.5 mV.

When X and Y are stimulated simultaneously, the postsynaptic neuron depolarizes by 1 mV, which is sub-threshold (below -55mV).

Therefore, when X fires 10 times and Y fires 10 times, the postsynaptic neuron will experience subthreshold summation and no action potential will be fired.

Answer:

destruction of natural habitats

Explanation:

First let's define our main terms or each answer choice.

1)Decreased deforestation - Deforestation is the action of clearing mass amounts of trees for human use such as farms, buildings, houses etc. So this answer is basically saying that as the human population increased the amount of trees that get destroyed will decrease.

2)Destruction of natural habitats - Natural habitats is simply the natural home of animals. So this answer is saying as the human population increases the more number of animals natural homes will be destroyed

3)Unchanged climate - Climate is basically the long term weather of an area. So this answer choice is saying that as the human population increases the climate will remain unchanged.

4)Increased biodiversity - Biodiversity is the different kind of life on earth usually regarding a specific habitat or ecosystem. So this answer choice is essentially saying that as the human population increases the types of life on earth increases.

What comes with increased human population?

As the human population increases the need for food, houses, water, jobs etc increases as well. Keep that in mind while looking at the answer choices.

Determining the answer

Why the answer isn't A

Rereading 1) and then what comes with increased human population we can most definitely rule out A. As human population increases the need for houses and jobs increases. In order to have a good enough supply of wood and land for these houses and buildings for these jobs, deforestation must occur. So as human population increases deforestation would increase as well.

Why the answer is B.

Rereading 2) and then looking at what comes with increased human population we can maybe say that B is correct. Looking back at the previous section we've already identified that mass deforestation must occur to satisfy the needs for wood and land for houses and jobs for the increased population. As we know many animals probably live in these forests and inside of the trees so many of these animals homes would be destroyed resulting in the destruction of natural habitats ( animals homes )

Why the answer isn't C

After rereading section 3) and what comes with increased human population we can rule out C. If an increase in human population results in deforestation the amount of CO2 released into the air increases as well. If you didn't know trees absorb CO2 which is bad for the atmosphere. Once destroyed the trees release the CO2 that they have absorbed. CO2 and other green house gases create holes in our atmosphere leading to a change in climate as the suns radiation travels through these little holes. This results in a change in temperature, increased natural disasters and the melting of ice on the poles which also leads to increased temperatures. Deforestation isn't the only cause of this ( gasoline from cars, burning of fossil fuels , pesticides and many other human caused actions result in this ). These are all human caused things so if the human population increases the amount of green house gase emissions would likely increase as well meaning the climate would no remain unchanged.

Why the answer isn't D

After reading section 4) as well as the section titled "why the answer is B" we can rule out D. In order for an increase in biodiversity to occur, natural habitats must be preserved ( remain untouched ) if deforestation occurs then natural habitats will be destroyed and biodiversity will never increase as many animals may not be able to find another sustainable habitat. Not only that but the question asks about a negative affect and biodiversity is a good thing.

b. Forward or reverse primers

Explanation:

Sanger sequencing is a technique of DNA sequencing based on the extension of DNA fragments with variable sizes terminated with dideoxynucleotides at the 3′ end. This technique was developed by Frederick Sanger in 1977. In Sanger sequencing, a short primer is added in order to bind by complementarity to the target DNA region of interest. Subsequently, a DNA polymerase adds nucleotides (A, T, C and G) in the 5'-3' direction. Finally, the extension of the DNA strand is stopped by adding dideoxynucleotides, which are nucleotide analogs (i.e., modified nucleotides) that act as DNA synthesis terminators.

When setting up a Sanger sequencing reaction, each reaction should include template DNA, nucleotides, dideoxynucleotides, buffer, DNA polymerase, and forward or reverse primers.

Sanger sequencing refers to a laboratory procedure that's used in the determination of DNA sequence by using dideoxynucleotides. Sanger sequencing is also known as dideoxy sequencing.

For Sanger sequencing to work, one needs two pieces of information that will be used to apply the strategy of sentence game to the sequencing of DNA. It should be noted that forward or reverse primers are required for the reaction.

Explanation:

2Mg + O2 → 2MgO

got it right on edge 2020

Considering the law of conservation of matter, the correct answer is third option: 2 Mg + O₂ → 2 MgO

The law of conservation of matter states that since no atom can be created or destroyed in a chemical reaction, the number of atoms that are present in the reagents has to be equal to the number of atoms present in the products.

Then, you must balance the chemical equation. For that, you must first look at the subscripts next to each atom to find the number of atoms in the equation. If the same atom appears in more than one molecule, you must add its amounts.

So, in the case of Mg + O₂ → MgO, you have:

The coefficients of each molecule below indicate the amount of each molecule for the reaction. This coefficient can be modified to balance the equation, just as you should never alter the subscripts.

By multiplying the coefficient mentioned by the subscript, you get the amount of each element present in the reaction.

So, balancing the O to obtain the same amount in the reactants and products you get:

Mg + O₂ → 2 MgO

So you have:

Since you still don't have the same amount of Mg on both sides, the equation is not balanced. Therefore, balancing the equation again:

2 Mg + O₂ → 2 MgO

So you have:

Now you have the same amount of each element on each side of the reaction, so the reaction is balanced.

Finally, the correct answer is third option: 2 Mg + O₂ → 2 MgO

Explanation:

When we see the reciprocal cross between a red-eyed female (homozygous) and a white-eyed male,we observe that none of the offspring will have white eyes. Additionally, the sex of the offspring will be half male and half female since the ratio of males to females is 1:1.

The reciprocal cross for a red-eyed female (homozygous) and a white-eyed male can be shown as follows:Female (XrXr) x Male (XwY). Females have two X chromosomes and males have an X and a Y chromosome. Red eyes are dominant to white eyes; therefore, we use Xr to represent red eyes and Xw to represent white eyes.

The offspring are as follows:All F1 females are heterozygous (XrXw).All F1 males are hemizygous (XrY).The F1 generation will have red eyes since the dominant allele is present.

None of the F1 individuals will have white eyes as the recessive allele is not present in the F1 generation.
