The nitrogenous bases which are the part of nucleotide codes for out traits. Nitrogenous bases are of two types: Purines and Pyrimidines.
What are Nitrogenous bases?Nucleobases are also known as nitrogenous bases. These are the nitrogen-containing biological compounds which form nucleoside units, which, in turn, are components of the nucleotides, with all of these monomeric units that are constituting of the basic building blocks of nucleic acids.
The ability of the nitrogenous bases to form base pairs and to stack one above the another leads directly to a long-chain helical structure such as ribonucleic acid (RNA) and deoxyribonucleic acid (DNA) molecules. Five nitrogenous bases include adenine (A), cytosine (C), guanine (G), thymine (T), and uracil (U). They function as the fundamental units of the genetic code in living organisms, with the bases A, G, C, and T being found in the DNA molecule while A, G, C, and U are found in the RNA molecule.

During sexual reproduction, each parent contributes
A
a double helix of chromosomes.
B
one strand of chromosomes, or half of the new organism's DNA.
C
a dominant gene and a recessive gene.
D
multiple mutated cells.
Answer:
[tex]\boxed {\boxed {\sf B. \ One \ strand \ of \ chromosomes \ or \ half \ of \ the \ new \ organism's \ DNA}}[/tex]
Explanation:
Sexual reproduction involves gametes. These are sex cells (sperm for males and eggs/ovum for females).
These sex cells are formed during meiosis. During this process, two rounds of cellular division occur, so there are four resulting haploid cells. Haploid means they contain half of the genetic information.
These cells are haploid because during fertilization, a sperm and egg fuse to form a zygote. Each parent contributes half of the DNA to create one complete set of DNA.
Therefore, the best answer choice is B. one strand of new chromosomes or half of the new organism's DNA.

What is the answer to it?
Answer:
Golgi body
Explanation:
A cell organelle is a structure found in a cell that plays a specific role or function. Some of the cell organelles in living cells include nucleus, mitochondria, chloroplast etc. Ideally, the NUCLEUS, which is the organelle that directs the processes of other organelles contain the genetic material called DNA, which is a type of nucleic acid.
However, some organelles like mitochondria, ribosome and chloroplast also contains nucleic acid.
- Mitochondria contains it's own DNA nucleic acid.
- Chloroplast, also contains its own DNA nucleic acid.
- Ribosomes contain RNA (ribosomal RNA and transfer RNA).

PLS HELP ASAP Select the word that means how easily water can move through a substance. Lesson 2.03 o particles permeability porosity
Answer:
permeability
Explanation:
dictionary definition: the state/quality of a material or membrane that causes it to allow liquids or gases to pass through it
in biology we use this term to describe the cell membrane, it is "semi-permeable" because it allows certain gasses and molecules to pass through
The water can easily move through a substance and it is called permeability. Hence, option B is correct.
What is permeability?The ability of molecules to pass through a biological membrane or barrier is known as biological permeability. Because cell membranes are selectively impermeable, substances cannot pass through the barrier without consideration. Some of the characteristics that affect permeability include polarity, hydrophobicity, charge, size, and shape.
The metabolic activities, survival, and potential use of the cell in both biotechnological applications and physiological systems are all greatly impacted by the cell membrane permeability, which controls the rate of solute transport into and out of the cell.
The water can easily move through a substance when the substance is permeable. Hence, option B is correct.

Which of the following describes how metamorphic rock forms?
A
Tectonic plate boundaries break apart an existing parent rock.
B
An igneous rock deep in the Earth is exposed to hot material.
C
Molten rock solidifies and hardens on top of the Earth’s crust.
D
A parent rock is baked and melted into liquid rock in the Earth.
An igneous rock deep in the Earth is exposed to high heat, high pressure, and hot mineral-rich fluids, by this process metamorphic rock forms, hence option B is correct.
What is a metamorphic rock?Metamorphic rocks are produced when rocks are exposed to high heat, and pressure, hot mineral-rich fluids, or maybe some combination of these factors, all these conditions are found deep on Earth.
In the deep of Earth, if an igneous rock deep in the Earth is exposed to hot material, this result forms a metamorphic rock.
This is also a result when rocks change their original shape and identity due to high heat or pressure, this pressure is only found deeper in the Earth.
Therefore, if an igneous rock deep in the Earth is exposed to hot material, it results in metamorphic rock.

Answer:
person 1 in row 3's genotype AA or Aa
Explanation:
the trait is recessive (given) which means in order to have it, you must obtain both alleles. in the pedigree, shaded shapes indicate people who have the trait, but person 1 in row 3 is not shaded so their genotype must be AA (dominant) or Aa (dominant leading) and their phenotype would not express the trait, because the dominant allele will "take over"

What are the 3 main processes common between terrestrial and aquatic ecosystems?
Answer:
Three main processes that are common between these are that they both make food through photosynthesis, they both perform transpiration, and they both need sunlight in order to process chemical energy.
I really hope this helped and have a great day! :)
The process that are seen in both terrestrial and aquatic ecosystems are;
Transpiration process
Photosynthesis for food synthesis
Energy through sunlight.
An ecosystem can be regarded as geographic area which contains plant as well as animals with other organisms and weather and landscape and they all carried out different functions so that bubble of life is formed.Ecosystem could be terrestrial as well as aquatic ecosystems.An aquatic ecosystem can be regarded as types of ecosystem containing body of water. In contrast to terrestrial ecosystems that is associated to land, there are Communities of organisms that their dependent is on each other as well as the environment all live in aquatic ecosystems.Aquatic ecosystems could contains body of oceans as well as lakes rivers, and stream.Terrestrial ecosystem can be regarded as community of organisms that dominate land, as well as interactions that exist between biotic as well as abiotic components in a given area. Some of terrestrial ecosystems are tundra, taigas as well as temperate deciduous forests and tropical rainforests.Some of the processes that can be attributed to both terrestrial and aquatic ecosystems are;
Making of their food could be through photosynthesis, this is the process whereby plant makes their food through the energy from sunlight.Sunlight is required as a source to process energy. Transpiration can be regarded as process involving movement of water through a plant, this could also encompass the evaporation of this water from aerial parts which could be in the leaves as well as stems and flowers.Therefore, both terrestrial and aquatic ecosystems have some process in common.

Entre los hijos de esta pareja hay algunos que muestran Rh+ y Rh-.
Si la madre es Rh-, entonces su genotipo es rr y solo tiene alelos recesivos r para pasar a la progenie.
Sabemos que el padre es Rh+, lo que indica que en su genotipo hay al menos un alelo dominante R. Puesto que la mitad de sus hijos tiene factor Rh-, podemos asumir que el hombre es heterocigoto para el tipo de sangre (Rr). De los contrario, de ser homocigoto dominante, toda la descendencia seria Rh+. El padre le hereda a la mitad de los hijos el alelo R y a la otra mitad el alelo r.

Si la madre es Rh- su genortipo es rr y solo puede heredarle a los hijos alelos recesivos, r.
El padre es Rh+, con lo que inferimos que el genotipo tiene al menos un alelo dominante R. Puesto que todos los hijos de esta pareja son Rh+, podriamos suponer que el padre es homocigoto para el tipo de sangre Rh+, heredandole a los hijos solo alelos dominantes.
