✎﹏☾✦☁️❣️ Briefly explain the process of photosynthesis .❣️☁️
Answer:
hope this will help u
Explanation:
photosynthesis is the process in which plant make their own food with the help of sunlight,water and carbon dioxide. water and carbon dioxide are raw materials in photosynthesis because they help to prepare their food.During photosynthesis, plants take in carbon dioxide and water from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.
Explanation:
PHOTOSYNTHESIS
This is a process in which green plants and other organisms make their own food from simple inorganic substances which are sunlight ,CO2 and chlorophyll.
Why do plants have trouble growing in space?
Answer:
The first challenge in growing plants in space is how to get plants to grow without gravity. This runs into difficulties regarding the effects of gravity on root development, providing appropriate types of lighting, and other challenges
Answer:
because, The first challenge in growing plants in space is figuring out how to get them to thrive in the absence of gravity. This presents difficulties in terms of the impact of gravity on root growth, as well as the provision of adequate lighting and other issues.
Explanation:
Gravity has an impact on root formation, but the scientists discovered that their space plants didn't need it to thrive. The space flowers showed common root growth patterns such as "skewing," where roots slant slowly as they branch out, when grown on a nutrient-rich gel in transparent petri plates.
Modern humans are the product of evolutionary processes which have occurred over millions of years . True or false?
Sorry for all of this, I’m having trouble with these questions!
Answer:
True to an extent.
Explanation:
Modern humans are the product of evolutionary processes. This is true to some extent.
What is evolution?
Evolution is defined as the theory in biology that various types of plants, animals, and other living things on Earth evolved from other preexisting types and that distinguishable differences are the result of modifications in successive generations.
There are basically four types of evolution.
Divergent evolutionConvergent evolutionParallel evolutionCoevolutionHumans are one of the best example of evolution.
Thus, modern humans are the product of evolutionary processes which have occurred over millions of years. This is true to some extent.

Scientists now classify all living things into 6 kingdoms. Which of the following groups of organisms is classified into the greatest number of kingdoms?
A. multicellular animals that are larger than humans
B. humans and other multicellular organisms that are about the same size as humans
C. plants and animals that are smaller than humans but still visible
D. organisms that are microscopically small and each made of a single cell
humans and other multicellular organisms that are about the same size as humans.
What are 6 kindgoms?
The greatest classification for all organisms in biological taxonomy is called a kingdom. In taxonomy, there are 6 kingdoms. These six kingdoms comprise all forms of life. Eubacteria, Archae, Protista, Fungi, Plantae, and Animalia are the six kingdoms.
Most scientists believed that all living things could be categorized as either plants or animals up until the 20th century. However, most biologists realized in the 1950s and 1960s that this approach was insufficient for fungus, protists, and bacteria.
A classification scheme known as the "Five Kingdoms" came to be acknowledged as the standard by which all living things may be arranged by the 1970s.
Therefore, humans and other multicellular organisms that are about the same size as humans.

A porcupine eats 3,000 J of plant material. Of this, 2,100 J is indigestible and is eliminated as feces, 800 J are used in cellular respiration, and 100 J are used for growth and reproduction. What is the approximate production efficiency of this animal?A) 3%B) 11%C) .03%D) 27%E) 33%
Answer:
A) 3%
Explanation:
Given;
total energy consumed by the porcupine, [tex]E_t[/tex] = 3,000 J
energy eliminated as feces = indigestible plant energy, = 2,100 J
internal energy for cellular respiration = 800 J
energy used by the animal for growth and reproduction = production energy of the animal = 100J
The approximate production efficiency of this animal is calculated as;
[tex]E_n = \frac{100 \ J}{3,000 \J} \times 100 \%\\\\E_n = 3.33 \%\\\\E_n \approx \ 3\%[/tex]
Therefore, the approximate production efficiency of this animal is 3 %

I need a Multiple Alleles trait for an animal!!!
Answer:
Fury can be a allele trait in an animal anything that you can see in the physical appearance on the animal can be a alleles trait
Answer:
Anything you see physically on an organism can be considered as an allele.
Explanation:
An allele is one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.
Let's use one example: a white bunny with red eyes. One allele for this animal would be that it has white fur color. Another allele would be its red eye color.
Let's use another example, but with two people. Person A has straight hair and freckles. Person B has curly hair and no freckles. Person A's alleles would be straight hair and freckles. Person B's alleles would be curly hair and no freckles.
Any physical characteristic trait on an organism can be considered as an allele for that organism.

Although the number of genes in the human genome is surprisingly low compared to less complex organisms, the number of possible products from those genes is greatly amplified by _____.a. coordinate control of genes on different chromosomesb. alternate arrangements of exons from a primary transcriptc. differential activation of genes in different cell typesd. each gene being activated by a unique combination of control elements and activator moleculese. the congregation in specific sites in the nucleus of genes involved in related metabolic processes, but on different chromosomes
Answer:
alternate arrangements of exons from a primary transcription.
Explanation:
Genomics refers to the scientific study of genes (DNA) found in living organisms such as humans and animals.
A genome can be defined as the complete set of hereditary instructions that is typically found in the deoxyribonucleic acid (DNA).
Genome imprinting can be defined as an epigenetic biological process in which a genomic domain or genes of a living organism is marked biochemically with information that is related to parental origin. Thus, it is a non-Mendelian inheritance i.e genome imprinting is typically independent of Mendelian inheritance.
Transcription can be defined as a process which typically involves re-writing the informations contained within a Deoxyribonucleic Acid (DNA) into a Ribonucleic Acid (RNA) by enzyme RNA polymerase.
Although, the number of genes contained in the human genome is surprisingly low in comparison with less complex organisms such as bacteria, protozoa, salmonella, etc.
However, the number of possible products from those genes is greatly amplified by alternate arrangements of exons from a primary transcription.
An exon refers to the coding portion of a gene that contains the information required for transcribing and translating (encoding) the final part of a mature RNA, after one or more DNA sequences (introns).
Simply stated, an exon is a nucleotide sequence in DNA and RNA used for encoding a part of the final mature RNA.
A nucleotide can be defined as an organic molecule which forms the building block of nucleic acid such as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
