Reproduction in plants can be by vegetative propagation, through the vegetative propagules like the rhizomes or tubers, asexual reproduction by the production of spores and sexual reproduction by the formation of the male and female gametes.

Spores are the agents of asexual reproduction in plants. They are formed in the non-seed-bearing plants like the liverworts, hornworts, mosses and ferns. The ferns are the group of vascular plants that reproduce by spores. The leaves of the ferns (fronds) contain numerous sporangia which produce tiny spores. When the sporangia breaks open, the spores are released and dispersed by the wind. On encountering favourable conditions of the environment, these spores grow into tiny plants called the gametophytes.

Answer: C) carbon dioxide and water.

Answer:

In snapdragon plants, phenomenon of incomplete dominance is observed.

Incomplete dominance is a type of inheritance in which the dominant allele can not express itself completely over the recessive allele.

It leads to the generation of intermediate phenotype in heterozygous condition.

Due to this reason, when two purebred snapdragon plants form red and white flowers are crossed, it results in the production of offspring all with pink flower that is, an intermediate phenotype of red and white.

Answer: C: Prophase 1

Crossing over occurs in the first division of meiosis. Crossing over of chromatid pair occurs in PACHYTENE stage of PROPHASE I.

The crossing over is the exchange of genetic material. The crossing over takes place due to exchnage od DNA segments between non sister chromatids of homologous chromosomes. This results in new allelic combinations in daughter cells.

Crossing over occurs during prophase I of meiosis and  is the first stage of meiosis, where the homologous chromosomes pair up and exchange genetic material.

The answer is (C)

The process is essential for creating genetic diversity in offspring.

The other phases of meiosis are:

Metaphase I: The homologous chromosomes line up along the equator of the cell.

Anaphase I: The homologous chromosomes separate and move to opposite poles of the cell.

Telophase I: The chromosomes arrive at the poles of the cell and the nuclear membrane reforms.

Prophase II: The chromosomes condense and the spindle apparatus forms.

Metaphase II: The chromosomes line up along the equator of the cell.

A) Tropical rain forest.

This is one of the myriad reasons that it is vital that we protect and preserve our rain forests.

Answer:

(A)- Tropical moist forests

Explanation:

Rainforests have high biodiversity because they are abundant in nutrients, energy and a favourable climate. Tropical rainforests have warm temperatures and lots of precipitation. The high-intensity sunlight provides energy for producers in the rainforest and supports a wide variety of plant growth.

Since there is a lot of sunlight, there is a lot of energy in the rainforest. This energy is stored in plant vegetation, which is eaten by animals. The abundance of energy supports an abundance of plant and animal species.

Explanation: I got it right on the test.

density doesn't matter, pictures aren't very scientific or accurate, and the number of bees doesn't matter

Answer:

The correct answer is option D.

Explanation:

Thermohaline circulation is the circulation of currents in the deep ocean due to the density of the water which is controlled by heat and salinity. Water in the ocean posses layers or defined boundaries based on the density which provides driving force to the deep ocean currents.

Formation of these layers is due to the sinking of the cold water in the basin which and ice formation which leaves the salt in the seawater ,therefore, increasing salinity. This increased salinity increases its density and the surface water is replaced by the sinking water causing deep ocean currents.

Thus, option D is the correct answer.

b) Water

Explanation:

Water is the most likely cause of soil erosion in most of the areas, where there are less trees. Hence, the option (b) is the correct answer.

Answer:

True

Explanation:

All living organisms store their genetic information using the same molecules (DNA and RNA). The information encoded by these molecules needs to be decoded through gene expression and the way in which it is done is through the GENETIC CODE, which comprises of all the codons that encodes an amino acid.

There are only 20 common amino acids in proteins. These amino acids are specified by a group of three nucleotides in the DNA/RNA molecule, called CODONS. Each of these codons specifies an amino acid, although more than one codon can encode a particular amino acid, since there are 64 possible codons that can encode these 20 amino acids (more than enough).

One of the characteristics of the genetic code is its universality i.e. The same genetic code is employed by every known living organism with little or no exceptions.

The same codon specifies the same amino acid in most known living organisms. A codon does not code for a different amino acid in another organism. It is universal that codon AUG codes for Methionine in most living organisms.

This same coding in all organisms is a convincing evidence that all organisms share a common evolutionary history.

It is true that most organisms contain the same codons, as the genetic code is nearly universal. This implies that the same codons code for the same amino acids in most species, underscoring the idea of a single common ancestor for all life.

The statement that most organisms contain the same codons is true. In molecular biology, a codon is a series of three nucleotide bases in DNA or RNA that provides the code for a specific amino acid. Importantly, this genetic code is nearly universal among all organisms, meaning the same codons direct the formation of the same amino acids in most species. This is foundational to how genetic information is transmitted and interpreted across life forms. For instance, the codon 'AUG' always codes for the amino acid Methionine in all organisms. This universality reinforces the idea of a single, common ancestor for all life.

Cleaving a flatworm into pieces would not kill the flatworm as each piece would turn into a new flatworm. The mechanism is known as fragmentation. In multicellular species, fragmentation refers to a kind of asexual reproduction in which a species gets cleaved into fragments.  

Each of these fragments forms into completely developed, mature individuals, which are similar to their parents. Fragmentation is also called splitting, it is a mode of reproduction witnessed in various species like molds, filamentous cyanobacteria, lichens, various plants, and animals like flatworms, sponges, sea stars, and some annelids.  

A flatworm wouldn't die when cut into pieces due to their ability for regeneration where they can grow back severed parts, a simple body structure that lacks major internal organs, and physiological processes that rely on diffusion and cell-to-cell junctions for nutrient and gas exchange.

Cutting a flatworm into pieces would not kill it because of its remarkable ability for regeneration. This means that if an individual is severed, it can regrow its head or tail, or even several heads if the planaria is cut lengthwise. Additionally, flatworms are capable of asexual reproduction where an entire organism can be regenerated from just part of it.

Another reason as to why a flatworm wouldn't die when cut into pieces is its physiological processes. Flatworms have an incomplete digestive system with an opening, known as the 'mouth', that is also used to expel digestive waste. This means they do not dependent on major internal organs to process their food. Furthermore, they do not have circulatory or respiratory systems, with gas and nutrient exchange dependent on diffusion and cell-to-cell junctions.

Lastly, flatworms have a simple body structure that doesn't contain any internal body cavities. Their bodies consist of three layers that give rise to various tissues, and the materials needed by the flatworm can easily diffuse through their bodies. So, no major organ would be lost if the flatworm is cut, and each piece can eventually grow into a new flatworm.

The correct answer is option a, that is, dendrites, cell body, axon hillock, axon, and axon terminals.  

The nerve cells or the neurons exhibit three parts, which conduct the activities of integration and communication, which are dendrites, axons, and axon terminals. The dendrites refer to the sections of the neuron, which attain stimulation in order to activate the cell. They transfer electrical messages to the cell body of the neuron for the functioning of the cell.  

From there the impulse is transmitted to the axon hillock, which is a unique component of the cell body that associates with the axon. Here the summation of the synaptic inputs is done before getting transmitted to the axon. Finally, the impulse reaches the axon terminals present at the end of the axons that make the association with other neurons.  

The correct order of the parts of neurons involved in the flow of information is axon terminals, axon hillock, axon, cell body, dendrites.

The cell membrane is the membrane that can be found in both eukaryotic and prokaryotic cells. It is the cell that separates the interior of the cell from the extracellular environment. It is a protective layer that allows only the selected ions and organic molecules to enter inside the cells and go out of the cell, hence is called as selectively permeable or semi-permeable membrane. This phenomena maintains the concentration of ions and molecules inside the cell and prevents dehydration, cell rupture due to high concentration.

Final answer:

When crossing a heterozygous round, yellow pea plant with a homozygous round but heterozygous yellow pea plant, we would expect two different phenotypes: round yellow and round green peas.

Explanation:

The student asked to determine the phenotypes of offspring when a pea plant heterozygous for round, yellow peas is crossed with a pea plant homozygous for round peas but heterozygous for yellow peas. The genotypes for round peas are given as R (dominant) and r (recessive), and for yellow peas as Y (dominant) and y (recessive). Therefore, the parental genotypes will be RrYy (heterozygous for both traits) and RrYY (homozygous for round and heterozygous for yellow).

To find the number of different phenotypes, you would conduct a Punnett square analysis. The possible combinations of these alleles would show the expected offspring's genotypes. Genotypically, we expect to see 1/2 of the offspring being R-Y- (either RrYy or RRYy, both resulting in round yellow peas since the R and Y alleles are dominant) and the other 1/2 being RrYY. This cross would therefore produce two different phenotypes: round yellow peas and round green peas if any recessive alleles come into play.

"The offspring of this cross are expected to show two different phenotypes.

To determine the number of different phenotypes expected in the offspring, we need to consider the genotypes of the parent plants and use the principles of Mendelian genetics.

The first parent plant is heterozygous for both round peas (Rr) and yellow peas (Yy). The second parent plant is homozygous for round peas (RR) but heterozygous for yellow peas (Yy).

The cross can be represented as follows:

RrYy (first parent) x RRYy (second parent)

When we perform a dihybrid cross, we can look at each trait separately:

For the shape trait (round vs. wrinkled):

- The first parent contributes either R or r with equal probability.

- The second parent contributes R (since it is homozygous RR).

For the color trait (yellow vs. green):

- The first parent contributes either Y or y with equal probability.

- The second parent contributes either Y or y with equal probability (since it is heterozygous Yy).

Now, let's look at the possible gametes for each trait:

- Shape: R and r (from the first parent), R (from the second parent).

- Color: Y and y (from both parents).

The possible combinations of gametes for the offspring are:

- RY, Ry, rY, ry

Since the second parent is homozygous for the round trait (RR), all offspring will inherit the R allele for round shape from this parent. Therefore, the shape of the peas in the offspring will be round regardless of the allele received from the first parent.

For the color trait, since both parents can contribute either Y or y, the offspring can have the following genotypes: YY, Yy, or yy. However, because the yellow color (Y) is dominant over green (y), the YY and Yy genotypes will result in yellow peas, while only the yy genotypes will result in green peas.

Therefore, the offspring will show two different phenotypes:

1. Round, yellow peas (from R_Y_ or R_Yy genotypes)

2. Round, green peas (from R_yy genotypes)

In summary, the offspring will exhibit two phenotypes: round, yellow peas and round, green peas."
