Answer:D, gene pool.
Explanation: relative frequency can refer to the proportion of a particular genotype or phenotype in a population.
Phenotype is the physical expression of the genotype.
Genotype is the specific form of the alleles of genes
Gene pool is the totality of genetic variations in a population

What general type of cell do fibroblasts make?
neural
blood
heart
tissue
Fibroblast is the cells mostly found in the connective tissues and maintain the structural organisation of the tissue framework.
General type of cell that makes fibroblasts are:
Option D. Tissue
This can be explained as:
Tissue specifically connective is responsible for producing the fibroblast.Fibroblasts are the cells that are an important factor in wound recovery.They also secrete collagen, fibronectin and fibrin. Cells adhere together with the help of fibrinogen and fibrin while collagen provides mechanical power.Therefore, tissues produce fibroblasts.

How do cells, tissues, organs, and organ systems work
together in a multicellular organism?
Answer:
Key points. Humans—and other complex multicellular organisms—have systems of organs that work together, carrying out processes that keep us alive. ... Cells make up tissues, tissues make up organs, and organs make up organ systems. The function of an organ system depends on the integrated activity of its organs.

What are 3 characteristics of producers
Answer:
The best examples of producers are plants, lichens and algae, which convert water, sunlight and carbon dioxide into carbohydrates.
Answer:
Producers make their own food. They do not have to obtain energy from other organisms. They obtain their energy from the sun and make food with that energy through the process of photosynthesis. Producers may also be called autotrophs.

Answer:
4 genetically different haploid cells
Explanation:
meiosis gives rise to four unique daughter cells, each of which has half the number of chromosomes as the parent cell.
4 genetically different haploid cells.
What is Meiosis?
In sexually reproducing organisms, meiosis is a kind of cell division that results in a reduction in the number of chromosomes in gametes (the sex cells, or egg and sperm). Body (or somatic) cells in humans are diploid, meaning they have two sets of chromosomes (one from each parent).
The egg and sperm that combine during fertilization must be haploid, or having only one pair of chromosomes, in order to sustain this state. Each diploid cell divides twice during meiosis to produce four haploid daughter cells, which are the gametes.
Nearly every human cell contains 46 chromosomes, 23 of which come from one of our parents and 23 highly similar chromosomes from the other parent.
Therefore, 4 genetically different haploid cells.

What is one way people have negatively affected land resources?
A) Habitat restoration
B) Urbanization
C) Terrace farming
D) Reforestation
Answer:
b
Explanation:
Urbanization is one way people have negatively affected land resources. Therefore, the correct option is B.
What is Urbanization?The process of urbanization occurs when the percentage of a country's population living in urban areas increases. This is a result of rural-urban migration, which occurs when people move from rural to urban areas in search of better job prospects, social services, and living standards. Urbanization has both beneficial and harmful effects on the environment and society.
On the plus side, urbanization can promote economic growth, better infrastructure, and greater access to social services, including healthcare, education, and social assistance. Additionally, it helps reduce stress on rural communities, which may experience issues of resource scarcity, resource overabundance, and environmental degradation.
Therefore, the correct option is B.

Explanation:
Donald is trying to get through a door but his friend Goofy is blocking the way using 15 N of force. Donald finally pushes on the door with 20 N and gets through knocking Goofy out of the way. Solve for net force.
Answer:
5 N
Explanation:
Goofy is blocking the way with 15 N force and Donald was only able to knock Goofy off using a 20 N force. The net force would be the difference between the applied force of Donald and that of Goofy.
Hence,
20 N - 15 N = 5 N
The net force is, therefore, 5 N.
