Photosynthesis takes place in the _______________ and releases __________________.
A. mitochondria, oxygen
B. chloroplast, oxygen
C. mitochondria, carbon dioxide
D. chloroplast, carbon dioxide
Answer:
B. chloroplast, oxygen
Explanation:
This is because plants take in the carbon, water, air,and it transforms the water into oxygen and carbon into glucose. So it absorbs light, and the chloroplasts are special structures that are responsible for that absorption of light, They are green, because of chlorophyll, which gives the green pigment to leafs
photosynthesis takes place inside them, so they can absorb light to start the process.

Please write the code of the transcribed RNA strand from this DNA:
ATTTGCATGCA
Answer:
UAAACGUACGU
Explanation:
You want us to transcribe ATTTGCATGCA. Remember that in transcription, we don't use thymine (T) we use uracil (U). This means that adenine (A) will pair with uracil (U). Let's begin:
A --> U
T --> A
T --> A
T --> A
G --> C
C --> G
A --> U
T --> A
G --> C
C --> G
A --> U
So, the answer is UAAACGUACGU
Answer:
UAAACGUACGU
Explanation:
When transcribing....
Adenine (A) Transcribes to Uracil (U)
Thymine (T) Transcribes to Adenine (A)
Cytosine (C) Transcribes to Guanine (G)
and Guanine (G) Transcribes to Cytosine (C)
So if the DNA strand, ATTTGCATGCA were to be transcribed
A would change to U
T to A
T to A
T to A
Etc.
We would end up with UAAACGUACGU

them but present in green leaves?
Answer:
the substance that they are missing is called chlorophyll, which all green leaves have
Substance missing from the unhealthy leaves are Chlorophyll.
Due to absence of chlorophyll the leaves do not absorb sun energy for photosynthesis. This leads to the leaves of plants turning yellow which eventually lead to the degradation of plantsWhat is chlorophyll?Chlorophyll is a pigment in the plants that provide them green color and help them to absorb energy from the sun and undergo the process of photosynthesis.

How do the chromosomes in gametes produced during meiosis differ from those in somatic cells produced during mitosis
Mitosis produces two diploid (2n) somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis produces four haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell.
MARK ME AS BRAINEST PLEASE. I WILL BEG YOU.
The chromosomes vary in that sister chromatids of each chromosome are genetically identical in a mitotically dividing cell, but sister chromatids are genetically distinct in a meiotically dividing cell due to crossing over in meiosis I.
What are chromosomes?Chromosomes are thread-like structures that are found within the nucleus of animal and plant cells.
Protein and a single molecule of deoxyribonucleic acid make up each chromosome (DNA). DNA, which is passed down from parents to offspring, contains the specific instructions that distinguish each type of living creature.
Each cell in humans normally contains 23 pairs of chromosomes, for a total of 46. Twenty-two of these pairs, known as autosomes, are identical in both males and females.
Meiosis produces haploid gametes, whereas mitosis produces somatic cells; meiosis requires two divisions, whereas mitosis requires only one division; mitosis produces genetically identical daughter cells, whereas meiosis produces genetically unique daughter cells.
Thus, this way, the chromosomes in gametes produced during meiosis differ from those in somatic cells produced during mitosis.

Como interactúan Los animales con el suelo El suelo con el agua Los animales con el agua Las plantas con el aire
Answer:
Todas estas cosas interactúan entre sí.
Explicación:
Los animales interactúan con el suelo porque el suelo proporciona hábitat, agua, aire y alimento para los animales que son necesarios para la supervivencia. El suelo interactúa con el agua absorbiendo agua que puede ser retenida por las partículas del suelo que necesitan las plantas y otros animales en el suelo. Los animales interactúan con el agua porque hay muchos animales que viven en el agua y también necesitan agua para sobrevivir. Las plantas interactúan con el aire mediante el intercambio de gases. La planta absorbe gas de dióxido de carbono del aire que se necesita para la fotosíntesis.

Which property of water is most responsible for plants being able to transport water from their
roots to their leaves?
A. the attraction between molecules
B. a capacity to dissolve many substances
C. the ability to form a low-density crystalline structure when frozen
D.
a capacity to absorb large amounts of energy as temperature increases
The attraction between molecules is property of water is most responsible for plants being able to transport water from their roots to their leaves. Thus option A is correct.
What do you mean by transportation plants?Transportation in plant is the crucial mechanism where water and other nutrients are transported from its roots to the tips of the leaves.
In plants three levels of transportation occurs, such as from one cell to another, within phloem and xylem if it is long-distance transport , solute and water by individual cells.
For the transportation plant have two organ called as xylem and phloem
Xylem which is a long but non-living tube arises from from the roots to the leaves via stem.
Here, water is absorbed first by the root hair and undergo osmosis and reaches the xylem. Now from xylem vessels water is transported to the leaves and finally evaporated by transpiration process.
Thus option A is correct.
