Explain science and engineering
The study of the natural and physical world is known as science. Engineering is the practice of using knowledge to plan, create, and maintain a process or product that addresses a problem or fills a need.
The utilization of contemporary equipment and technology in agriculture is referred to as modern farming methods. These techniques concentrate on increasing output utilizing HYV seeds, although this irrigation demands contemporary equipment like tractors and threshers. The majority of foreign countries are using current technologies to their advantage in agriculture. Farmers are reaping greater benefits from using this approach and are prepared to increase their produce efficiency.
Modern agriculture's overarching goal is to create an agricultural system that generates excellent harvests, in significant quantities, and with the least amount of pressure possible. As agricultural production increases over the long term, this cycle is clearly seen in the region.

in a pond that experiences succession, what relationship would you expect regarding changes in species richness over time?
In a pond that experiences succession, species richness increases over time.
During succession, species diversity declines. A large number of species that enter the canopy through tiny holes and a comparatively small number that regrow in the huge clearings are characteristics of communities where such large patches are uncommon. Following a significant disturbance, diversity grows throughout the succession phase.
New species enter a region at each stage and may displace the ones that came before them, frequently as a result of environmental modifications produced by the preceding species. The community may eventually attain a condition of relative stability and stop shifting in composition.
Hence, species richness increases as result of succession.

The theory that those who adapt best to the environment will have a greater chance of surviving and passing on their genes is known as Natural selection.
Natural selection is one process of evolution. Creatures with more environmental adaptation have a better chance of surviving and passing on the genes that gave them an advantage. This process causes species to change and diverge throughout time.
Natural selection is a technique used to adapt and transform populations of living things. People in a population are naturally diverse, which means that every person is distinctive in some ways. Due to this diversity, some people have traits that better suit their environment than others. One of the most important aspects of evolution is the modification of a population's inherited traits over successive generations.

n pea plants, the allele for purple flowers, p, is dominant over the allele for white flowers, p. which conclusion about phenotype and genotype is possible?(1 point)
Dominant and recessive are used in the inheritance pattern of traits. Dominant traits mask the expression of recessive alleles whereas recessive traits can be expressed when two copies of allele is present.
What is the conclusion about phenotype and genotype?It is given that purple flower is dominant and white flower is recessive in pea plants. Hence, presence of at least one P allele will give purple color (dominant phenotype) to the flower. Therefore, the PP is a homozygous dominant genotype. Hence, the phenotype of PP is purple color.
Genotype of the purple (phenotype) flower is PP and that of white flower (phenotype) is pp.
As the purple flowers are dominant over the recessive, their genotype would be PP or Pp. White flowers phenotype would be white and genotype pp because they are recessive.

Construct a food chain. Label the producer, primary consumer, secondary consumer, and tertiary consumer. An owl eats a snake, the snake eats a squirrel, the squirrel ate a nut.
In the example, the producer is a nut, the primary consumer is a squirrel, the secondary consumer is a snake, and the third consumer is an owl.
What is the consumer in biology?Any organism that is unable to produce its own nourishment is a consumer. Consumers must eat from producers or other consumers in order to exist. Because they are herbivores, deer can only consume grass (Producers). A bear is another example of a consumer. 1. One who purchases products or services for personal use or possession as opposed to selling or use in production or manufacturing. 2. A heterotrophic organism in a food chain that consumes other organisms or organic substances.
Which organism is the consumer?The organisms that eat the producers are the principal consumers. They are many and frequently little in size. Herbivorous animals are the main consumers (vegetarians). The organisms known as secondary consumers are carnivores that consume the prime consumers.
Briefing:As a result, the food chain in this instance is nut—>squirrel—>snake—>owl.

why do organisms that perform photosynthesis require water and sun light?
Answer:
Explanation:
Photosynthetic organisms need light because this is the source of the energy that is transformed to chemical energy by chlorophyll. These organisms need water because the electrons that are excited in chlorophyll and passed to the electron transport system are replaced with electrons from a split water molecule. Hydrogen is used to form the proton gradient across the thylakoid membrane. The electrons take from the oxygen molecules in water release an oxygen gas into the atmosphere which makes living possible for us.
In pea plants, the allele for smooth pods (S) is dominant over the allele for constricted pods (s).
Which of the following pairs of terms are correctly matched?
Choose 1 answer:
Option d is correct because pea plants with the dominant S genotype have smooth and constricted pod phenotypes, which are controlled by the S gene.
What distinguishes a genotype from a phenotype?A physical observation of a trait under the control of a gene is called a phenotype.
genotype, on the other hand, is a genetic observation that cannot be physically seen.
The dominant allele is the one that controls a plant's phenotypic characteristics; the other allele, which cannot express itself, is always present in a group, but only the dominant will manifest itself.
If the smooth allele is dominant over the other in a pea plant, it manifests in allelic combination and hides the expression of constricted pods.

Phenotypes for:

Can you also provide an explanation? I want to actually know how to figure this out myself.
Assume that we have the dominant allele 'D' and the recessive allele 'd'. Lets make the example that the gene these encode for the fake disease called 'Fake Disease'. The recessive allele 'd' encodes for if you HAVE the disease. The dominant allele encodes for NOT having the disease. You get passed on a version of this allele from both your parents and hence any individual will have the genotype of 'XX' (basically your genotype will be a combination of the two alleles dependent on what you got from your parents). ALSO for a recessive allele to be expressed in the phenotype (definition below) you need to have two copies of it because other wise the dominant allele 'D' will 'hide' the occurance of the single 'd' allele.
Homozygous (the prefix 'homo' means SAME).
Heterozygous (the prefix 'hetero' means DIFFERENT).
Genotype = the genes you have in your genome
Phenotype = what trait is expressed due to what genes you have
Homozygous dominant = SAME of the Dominant allele
- Genotype: DD (the two alleles you have are the same and are both the dominant alleles)
- Phenotype: Does not have Fake Disease (as the recessive 'd' allele encodes for this and the individual does not have two of the 'd' the disease is not expressed in the genotype)
Heterozygous = DIFFERENT alleles
- Genotype: Dd (you get one copy of each allele but both are different from each other)
- Phenotype: Does not have Fake Disease (the dominant allele 'D' is what it is called 'dominant' it dominants over the recessive allele and will cover the expression of the recessive allele)
Homozygous Recessive = SAME of the Recessive Allele
- Genotype: dd
- Phenotype: Does have Fake Disease (having two recessive alleles of a trait means that it is expressed in the individual.

how much physical factors such as temperature and salinity affect organisms is determined by the: group of answer choices environmental resistance carrying capacity ability to osmoregulate range of tolerance of the organisms
Physical factors such as temperature and salinity affect organisms is determined by the carrying capacity.
The physical and biological world where we live in - Environment. Each level of food chain where transfer of energy takes place - Trophic level. The physical factors like temperature, rainfall, wind and soil of an ecosystem - Abiotic factors. One of the most important abiotic factors influencing species composition in marine environments is salinity. Low-salinity (hypoosmotic) stress, which is common in many estuaries and coastal areas, can cause severe physiological stress in marine animals, affecting survival, immune responses, metabolism, protein function, and other cellular processes. Under moderate hypoosmotic stress, increased osmoregulation costs are met by increasing the routine metabolic rate or re-allocating energy to osmoregulatory processes. This, however, limits the potential for growth and reproduction, as well as, ultimately, fitness. The depletion of the organic osmolyte pool caused by low salinity has been proposed to set a critical boundary in osmoconforming marine invertebrates.
Desalination has been predicted for many coastal areas as a result of ongoing climate change, so it is critical to gain a better understanding of the mechanisms that limit salinity acclimation ability.
