Angiosperms are flowers and seed producing plants and their seeds are enclosed in ovary.The angiosperms are vascular seed plants in which the ovule (egg) is fertilized and then develops

into a or become a seed in an enclosed hollow ovary. They are most diverse and largest group of animal kingdom.

Some angiosperms are autotrophs that uses carbondioxide, water and sunlight energy to produce their own food and releases oxygen.

Examples include maize, rice..

Some angiosperms are saprophytic which obtain energy from dead and decaying matter in the soil. They form a symbiotic relationship with fungi. Example is Neottia.

Some angiosperms are parasitic and they attach to their host through haustoria their by feeding on the host and causing harm on the host.

The symbol for an atom can be written to show its mass number at the top, and its atomic number at the bottom. To calculate the numbers of subatomic particles in an atom, use its atomic number and mass number: number of protons = atomic number. number of electrons = atomic number.

Vanessa has a better absolute threshold and more sensitive difference threshold than Carlton, and Carlton has an impaired absolute threshold.

Carlton and Vanessa were lab partners for a biology class and were asked to run a smell test experiment on each other.

Vanessa was excellent at noticing the difference between various intensities of vanilla and evergreen.

Carlton, on the other hand, couldn't distinguish the difference in the intensities of both vanilla and evergreen, though he could tell the smells of both.

Hence, based on the information provided in the scenario, it can be inferred that Vanessa has a more sensitive difference threshold than Carlton, and Carlton has an impaired absolute threshold.

The two significant aspects that are involved in the scenario are absolute threshold and difference threshold.

The absolute threshold is the smallest quantity of a stimulus that an individual can detect, whereas the difference threshold is the minimum difference in stimuli that an individual can detect.

Carlton could recognize the stimuli's smell but not the difference in the intensity of vanilla and evergreen.

This shows that Carlton has an impaired absolute threshold.

He could not detect the smallest quantity of a stimulus to differentiate between the smells.

Vanessa was quite good at noticing the difference in the intensities of vanilla and evergreen.

This means that Vanessa has a more sensitive difference threshold than Carlton. She could detect the minimum difference in stimuli required to differentiate between smells.

Vanessa also has a better absolute threshold than Carlton as she could detect the smallest quantity of stimulus required to detect the smells.

CCS is not viable, despite the fact that it can reduce emissions at the source and that point sources make it easier to remove CO2.

They can be divided into three groups: oxy-fuel combustion systems, post-combustion carbon capture (the main technique utilized in current power plants), and pre-combustion carbon capture.

The benefits of adsorption-based post-combustion CO2 capture technology are cheaper CO2 separation costs, decreased regeneration energy needs, and minimized pressure losses, which guarantee a relatively good performance in the capturing process.

Explanation:

Answer:

it can't be used to make a protein in that cell.

Explanation:

If a gene is not transcribed in a cell, it can't be used to make a protein in that cell. If a gene does get transcribed, it is likely going to be used to make a protein (expressed). In general, the more a gene is transcribed, the more protein that will be made.

The transcription is affected as when the gene has not been transcribed the protein will not make. When a gene is transcribed, protein synthesis can happen.

Gene expression begins with transcription. To create an RNA molecule, the DNA sequence of a gene must be copied. RNA polymerases, which join nucleotides to create an RNA strand, carry out transcription (using a DNA strand as a template).

A gene cannot be used to produce a protein in a cell if it is not transcribed there. If a gene gets transcribed, it will probably be used to produce a protein (expressed). In general, more protein will be produced the more a gene is transcribed.

Therefore, the transcription is impacted since the protein cannot be produced if the gene is not transcribed. Protein synthesis can take place when a gene is transcribed.

"The derived shared characteristic 'Terrestrial during all stages' should be placed at the base of the tree diagram."

SupThe characteristic "Terrestrial during all stages" is a shared characteristic among all five species being compared in the branching tree diagram. This means that it is a characteristic that all of these species have in common, and therefore it is likely that it was present in their common ancestor.

Since the base of the tree represents the common ancestor of the species being compared, it makes sense to place this characteristic at the base of the tree. This also helps to show that this characteristic is a defining trait of the group of species being compared and that it has been present in their lineage since their common ancestor.

The correct answer is - Photosynthesis takes carbon from the atmosphere and brings it to the geosphere and into plants.

Explanation:

Photosynthesis is the process that involves converting light energy to chemical energy stored in the form of sugars with the help of carbon dioxide and water as reactants.

The carbon is pulled from the atmosphere in the form of carbon dioxide for the process to the geosphere and then used by the plants (biosphere). In plants, it is trapped by the chlorophyll present in chloroplasts and water is entered in the light-dependent reaction and carbon dioxide is used in the light-independent reaction.

Answer:

prophase, prometaphase, metaphase, anaphase, and telophase.

Explanation:

the frequency of the heterozygote (Bb) in the population is approximately 0.4431, or 44.31%. To determine the frequency of the heterozygote, we first need to determine the frequency of the blue-eyed homozygote and the brown-eyed homozygote.

Given that 25% of the individuals have blue eyes, we can infer that the frequency of the blue-eyed homozygote (bb) is 0.25, or 25% (since blue is recessive). Therefore, the frequency of the brown-eyed homozygote (BB) can be calculated as 1 - 0.25 = 0.75, or 75%.

Now, let's denote the frequency of the heterozygote (Bb) as p. Since there are only two alleles in the population (B and b), the sum of the frequencies of all genotypes must equal 1.

The frequency of the heterozygote can be calculated using the equation:

2pq + p^2 + q^2 = 1,

where p represents the frequency of allele B, and q represents the frequency of allele b.

Since brown eyes are dominant, the frequency of the brown allele (p) can be calculated as the square root of the frequency of the brown-eyed homozygote (BB), which is 2*0.75*0.25

Therefore, the frequency of the heterozygote (Bb) can be calculated as:

2(0.866)(0.134) + (0.866)^2 + (0.134)^2 ≈ 0.4431.

Rounding this value to four decimal points, we get a frequency of approximately 0.4431 for the heterozygote.
