Answer:
the answer is D
Explanation:
hope this helps:)
Charles Darwin noticed that the finches had beaks of different sizes and shapes that were suited to the available food. Option D is correct.
Changes in their beak size and shape have allowed them to adapt to different food sources: seed, insect, cactus flower and fruit, or even bird’s blood. Adaptive radiation is a well-known feature of the Galapagos finches.
Darwin concluded that these differences allowed the finches to better adapt to the food in their specific habitat - thin sharp beaks where the birds feed on insects and grubs and large claw-like beaks where they feed on buds, fruits, and nuts.
So the correct option is D.

A. Ribosome
B. Mesosome
C. Plasmid
D. Nucleus
Answer:
D
Explanation:
i think this is the answer because the nucleus contains threads of DNA called chromosomes.which can help in a genetic experiment.
I hope this helps
In the given context, Nucleus would help in obtaining the copies of the gene.
The nucleus controls and regulates the activities of the cell and carries the genes, structures that contain the hereditary information.
What is Nucleus?In cell biology, the nucleus is a membrane-bound organelle found in eukaryotic cells.
The nucleus was discovered by Robert Brown in 1831.
Nuclear DNA is a multiple long linear molecules in a complex with a large variety of proteins, such as histones, to form chromosomes. The genes within these chromosomes are structured in such a way to promote cell function.
The nucleus maintains the integrity of genes and controls the activities of the cell by regulating gene expression and thus control the center of the cell.
The main function of the cell nucleus is to control gene expression and mediate the replication of DNA during the cell cycle.
Nucleus houses an organism’s genetic code, which determines the amino acid sequence of proteins critical for day-to-day function, it primarily serves as the information center of the cell has been found that replication happens in a localized way in the cell nucleus.
What is Ribosomes?A ribosome is a complex molecular machine found inside the living cells that produce proteins from amino acids during protein synthesis or translation. The process of protein synthesis is a primary function, which is performed by all living cells.
Ribosomes are specialized cell organelles and are found in both prokaryotic and eukaryotic cells. Every living cell requires ribosomes for the production of proteins.
This cell organelle also functions by binding to a messenger ribonucleic acid (mRNA) and decoding the information carried by the nucleotide sequence of the mRNA.
They transfer RNAs (tRNAs) comprising amino acids and enter into the ribosome at the acceptor site. Once it gets bound up, it adds amino acid to the growing protein chain on tRNA.
What is Mesosome?Mesosome is formed by an extension of the plasma membrane into the cell wall. These extensions are usually in the form of vesicles, tubules, and lamellae.
The main use of mesosomes are:
- Synthesis of a cell wall.
- DNA replication.
- Distribution of daughter cells, respiration, secretions, etc.
What is Plastid?Plastids are double-membrane organelles which are found in the cells of plants and algae.
Plastids are responsible for manufacturing and storing of food. These often contain pigments used in photosynthesis and different types of pigments that can change the color of the cell.
Different types of plastids with their specialized functions are:
- Chloroplasts
- Chromoplasts
- Gerontoplasts
- Leucoplasts

What kind of rock is this?
igneous
Where would this rock most likely be formed?
To which group of rocks would this rock belong?
Rocks can be classified based on texture. The
size of the grains in a rock affects its texture.
Coarse-grained rocks have large grains, and fine-
grained rocks have small grains.
Rocks formed from magma under Earth's surface
have larger grains than rocks formed from lava
on Earth's surface. This is because magma cools
slower underneath the ground than it does above
ground.

Hi, can someone help me these few questions! Will mark as brainliest! Thanks
Answer:
a)the process is binary fission
b)The stages involved are:
The parent cell first grows bigger by increasing the amount of cytoplasm
the DNA replicates and the nucleus undergoes mitosis, resulting in the formation of two daughter nuclei
the cell membrane constricts thereby dividing the cytoplasm in two so that each nucleus is surrounded by it's own cytoplasm
the two daughter cells separate.
c)the advantage is that offspring take short time to mature
the disadvantage is that it leads to overcrowding and competition for resources.

Aquaporins result in a combination of positive charges intracellularly and negative charges extracellularly
What are Aquaporins?
Aquaporin is a group of membrane proteins found in cell membranes and selectively permit water to pass into and out of the cell. Also known as water channels, aquaporins are integral membrane pore proteins. Aquaporins are found in plants, bacteria and animals. They are observed in the vacuolar membranes and plasma membranes. The basic function of most aquaporin is to transport water across cell membranes in response to osmotic gradients created by active solute transport. Aquaporins enable passive transport which means they allow the movement of molecules across a cell without using energy.

In which order will free nucleotides add on to a single strand of DNA with the sequence ATTGCA during DNA replication? (2 points) O Uracil, adenine, adenine, cytosine, guanine, uracil Adenine, thymine, thymine, guanine, cytosine, adenine Thymine, adenine, adenine, cytosine, guanine, thymine O Guanine, cytosine, cytosine, adenine, thymine, guanine
Adenine, thymine, thymine, cytosine, guanine, and adenine is the correct order in which nucleotides add on single strand DNA.
What is DNA replication?The process of DNA replication is crucial for cells to divide and create an exact copy of their DNA. Enzymes like helicase play a vital role in unwinding and separating the two strands of the double helix, creating a replication fork that serves as the starting point for this process. As DNA polymerase adds nucleotides to the new strand using the existing strand as a template, it follows specific rules of complementary base pairing: adenine (A) pairs with thymine (T), while cytosine (C) pairs with guanine (G).
What will be order of nucleotides to add on single strand of DNA?During DNA replication, the order in which free nucleotides will add on to a single strand of DNA with the sequence ATTGCA is crucial. The correct sequence of nucleotides that will bind to this template strand is adenine (A), thymine (T), thymine (T), cytosine (C), guanine (G) and adenine (A). This follows the complementary base pairing rules where A pairs with T and C pairs with G. By following these rules, the newly synthesized strand will have a correct sequence of ATTTGC, ensuring accurate replication.
