Which cell types are found in fibrous connective tissue?.
Answer:
fibroblast,plasma cells,leukocytes, mast cell etc
Fibroblasts are found in fibrous connective tissue.
What is fibrous connective tissue?Fibrous connective tissue, often known as FCT, is one of the many forms of connective tissue. Collagen, a protein recognized for providing stability and strength, makes up the majority of this high-strength, somewhat stretchable tissue.
Our muscles, bones, and skin are just a few examples of where collagen may be found in our body and how it supports us. Water and polysaccharides, which are intricate strands of carbohydrates, are the other two key components of FCT, both of which function to support.
Our bones and internal organs are mostly supported and shock-absorbed by fibrous connective tissue. It is also known as thick connective tissue and is present in the tendons, ligaments, and dermis. Fibrous connective tissue can interact with dental implants and is a significant component of the oral anatomy in dental applications.
Therefore fibroblasts are found in fibrous connective tissue.

Which process provides plants with the glucose needed for cellular respiration?.
Answer:
Photosynthesis is the process that plants use in the presence of sunlight to convert carbon dioxide taken in by their leaves and water taken in through the roots to produce oxygen and sugar (glucose).
manatees, aquatic mammals inhabiting florida’s rivers and coastal waters, swim close to the surface and are frequently killed in collisions with boats. to address the problem, boat traffic in manatee-populated waters is being required to maintain very low speeds. unfortunately, manatees are unable to hear low-pitched sounds and a boat’s sound lowers in pitch as the boat slows. therefore, this approach may in fact make things worse rather than better.
Fast-moving boat traffic can disturb or harm water hyacinth beds because the water hyacinth that manatees feed on develops best in water that is practically motionless.
In the scenario described in the question, it is said that manatees cannot hear the sluggish boats' low-pitched sounds, which could lead to more crashes and fatalities.
The response, if accurate, raises doubt about the findings since it makes sense for the boats to slow down even though the likelihood of hitting a manatee increases because the hyacinth that manatees eat grows best in calm water.

____ indicates that less than 100% of individuals with a mutant genotype have a mutant phenotype, while ----indicates that the severity of a mutant phenotype differs among individuals with the same mutant genotype. A) Variable expressivity, incomplete dominance B) Incomplete penetrance, variable expressivity C) Codominance, incomplete dominance D) Variable expressivity, incomplete penetrance
Variable expressivity, incomplete penetrance indicates that less than 100% of individuals with a mutant genotype have a mutant phenotype, meaning that some individuals may carry the mutated gene but not show any physical signs or symptoms.
Variable expressivity, on the other hand, indicates that the severity of a mutant phenotype differs among individuals with the same mutant genotype. This means that individuals with the same genetic mutation may display different levels of symptoms or physical manifestations of the condition.
Understanding these concepts is important for genetic counseling and predicting the likelihood of passing on genetic disorders to offspring.
Therefore, option D is the correct answer.

if genes are on different chromosomes, the law of independent assortment states that -
gene pairs always stay together
half an organism's gametes have one allele per pair
gene pairs segregate randomly and independently of each other.
one allele is always dominant
Answer:
Gene pairs segregate randomly and independently of each other.
Explanation:
Genes are the basic units of hereditary and are located on chromosomes. According to Gregor Mendel's law of independent assortment which states that the alleles of two (or more) different genes are sorted into gametes independently of one another. This means that the allele a gamete receives for one gene does not influence the allele the same gamete receives for another gene.
For example, in a the pea plants used by Mendel in his studies, the genes for seed shape and flower color were inherited independent of each other by the offspring of the parent pea plants. Therefore, Mendel concluded that the inheritance of each trait was independent of the other.
Answer:
gene pairs segregate randomly and independently of each other
Explanation:
According to the Law of Independent Assortment, if two genes are on different chromosomes, then the alleles for these genes separate independently of each other during the formation of eggs or sperm.
This means that genes separate independently of one another. This explanation most closely matches C) gene pairs segregate randomly and independently of each other.

Identify structures c, d, and e and explain how they work together to perform a specific process within the cell.
structures c, d, and e and the explanation of how they work together to perform a specific process within the cell as follows-
What is cell?Cell is an organism's basic structural, functional, and biological unit. Cells are the smallest living unit of life and are the building blocks of all living things, including plants and animals.
Structure C is the endoplasmic reticulum (ER). It is a network of membrane-enclosed channels that extends throughout the cell. It is responsible for transporting proteins and other molecules between the nucleus and other parts of the cell.
Structure D is the Golgi apparatus, which is a membrane-bound organelle that acts as a sorting and packaging hub for molecules that are manufactured within the cell. It receives proteins and other molecules from the ER and modifies and packages them for export to other parts of the cell.
Structure E is the lysosome, which is a membrane-bound organelle that contains enzymes to break down and recycle unwanted or damaged molecules within the cell. The lysosome works together with the Golgi apparatus to ensure that proteins and other molecules are properly packaged and delivered to their destination. Together, these three structures work together to regulate the movement and processing of molecules within the cell.

Why did finding Mesosaurus fossils in South America and Africa support the hypothesis of continental drift?
F. Mesosaurus could only have ended fossilized on both continents if they were once together.
G. Mesosaurus was unable to swim across oceans, so the fact that its fossils were found on distant continents suggested those continents had once been fused together and later moved apart.
H. Mesosaurus is now found in colder parts of the world, which means the continents have drifted since the fossils were made.
I. Mesosaurus wasn't found in Asia, which Wegener thought was the only stable continent that hadn't moved.
Answer:
G
Explanation:

Gametes produced by the parents are shown along the __________________ and _______________ sides of the Punnett square.
Answer:
Vertical and horizontal
Explanation:
A punnet square is a tabular chart used in genetics to display the genotypic composition of the offsprings of two parents. To construct a punnet square, the alleles of the gametes produced by the parents is required.
The gametes produced by each parent via meiosis are placed along the vertical and horizontal sides of the punnet square. For example, if a cross occurs between two parents with the following genotype: AaBb and AAbb. The parents will produce the following gametes:
AaBb - AB, Ab, aB, ab
AAbb - Ab, Ab, Ab, Ab
These gametes produces by each parent will be placed along the sides (vertical and horizontal) of a punnet square to determine the genotype of the offsprings that will be produced.

How might the manipulation of DNA or RNA be used to treat disease?
Answer: With gene therapy
Explanation:
Manipulation of DNA or RNA is used to treat disease with gene therapy. This type of therapy is introducing genetic material into cells because it should compensate for abnormal genes or it should also make a beneficial protein.
Gene therapy is able in some cases to introduce a normal copy of the gene and after that, it can restore the function of the protein.

if heterozygous round crossed with homozygous round produce 2400 plant how many plant are pure round
If heterozygous round plant is crossed with a homozygous round plant, then it will produce 2400 plant from which 1200 plants were pure round i.e., homozygous (RR).
What is Inheritance?Inheritance is the transfer of characters from the parent generation to the offspring. It takes place through the DNA which contains chromosomes and genes. The genes are responsible for the development of various characteristics in the daughter generation.
According to Mendel's genetics, for each character or gene a pair of contrasting alleles which code for different phenotype is present.
Here, a heterozygous round plant (with two different alleles) is crossed with a homozygous round plant, which results into the production of 2400 plants in the F1 generation.
Therefore, the total number of plants which are pure round can be calculated by Punnett square.
Pure round plants are the plants which are homozygous (RR) and pure wrinkled plants are (rr).
Therefore, the number of plants which are pure red = 1/2 of the total plants or 50% of the total plants.
Thus, number of pure round plants = 1/2 × 2400
Number of pure round plants = 1200

Immunity is comprised of both innate and acquired resistance.True or False
True. Innate and acquired resistance are both components of immunity. Innate immunity refers to a person's innate, non-specific defensive systems that give rapid.
but temporary, protection against a wide range of infections. This comprises physical and chemical barriers like skin, mucous membranes, and stomach acid, as well as cells and proteins like natural killer cells and complement proteins that can identify and respond to external invaders. Acquired immunity is the unique resistance that develops after being exposed to a specific disease, either naturally or by vaccination. Acquired immunity is the process by which the immune system is activated to develop particular antibodies and memory cells that can detect and respond promptly to recurrent infections with the same pathogen.

A.cells always stay the same.
B.cell division allows or organisms to grow and repair damaged parts.
C.food is made during photosynthesis, and energy is produced from during respiration.
D.materials move into and out of the cells though the cell membrane.
Answer:
A.cells always stay the same.
Explanation:
Homeostasis is the ability of an organism to maintain a stable internal state despite changes in external conditions. The process of homeostasis is important to the survival of both unicellular and multicellular organisms, as mentioned in this question.
Examples of homeostatic process undergone by organisms include:
- Cell division, which allows organisms to grow and repair their damaged parts.
- Making of food during photosynthesis, and production of energy during cellular respiration. This two processes are necessary for the survival of organisms as one produces food and the other synthesizes energy.
- Movement of materials into and out of the cells though the cell membrane, which is required to bring in needed substances and remove unwanted ones.
However, a cell staying the same does not depict any HOMEOSTATIC PROCESS.
