Answer:
Plant breeding is the purposeful manipulation of plant species in order to create desired genotypes and phenotypes for specific purposes. Plant genetic is is the study of genes, genetic variation, and heredity specifically in plants.
The seed method involves selecting plants with desired traits and breeding them to produce offspring with those traits and the biological method involves using mutation breeding, tissue culture, and genetic engineering to create new plant varieties.
What is seed and biological methods of breeding?The seed method and the biological method of breeding are two approaches that are used to develop new plant varieties.
The seed method involves selecting plants with desired traits and breeding them to produce offspring with those traits. This can be done through various techniques, such as crossbreeding, inbreeding, and hybridization. The seed method relies on the transfer of genetic material through the seed, and it is often used to develop new varieties of crops that are well suited to specific growing conditions.
The biological method of breeding involves using techniques such as mutation breeding, tissue culture, and genetic engineering to create new plant varieties. This approach involves altering the genetic makeup of plants in order to introduce new traits or to enhance existing ones. The biological method can be more precise and faster than the seed method, but it also involves more complex techniques and may be more expensive to implement.

Sexual reproduction increases the genetic variation of a species because:
Answer:
Sexual reproduction increases the genetic variation of a species because it involves combining of genetic materials of two parents/individuals to form an offspring.
Explanation:
Sexual reproduction is a type of reproduction that involves formation of an offspring by combination of male and female gametes. Each gamete carries a haploid set of chromosomes. When gametes from both the parents combine, a zygote is formed which has a diploid set of chromosomes. So, sexual reproduction involves combination of genetic materials of two different individuals, hence, it leads to genetic variation.

Brad is swimming in the ocean on a hot sunny day. he finds the water to be much colder than the sand on the beach, even though the sun is warming them both. identify the reasons for brad’s observation. the water is colder than the sand because it requires more to change temperature. this is because the water has a higher than the sand.
Answer:
The sea has a higher specific heat capacity than the sand meaning it takes more energy to heat up. The sand has a lower SHC so it requires less energy to heat up therefore heats faster and Brad will observe the sand to be hotter than the sea
The sea has a higher specific heat capacity than the sand meaning it takes more energy to heat up.
What do you mean by specific heat capacity?The specific heat capacity is defined as the quantity of heat (J) absorbed per unit mass (kg) of the material when its temperature increases 1 K (or 1 °C), and its units are J/(kg K) or J/(kg °C).
In thermodynamics, the specific heat capacity of a substance is the heat capacity of a sample of the substance divided by the mass of the sample, also sometimes referred to as massic heat capacity.
For liquid at room temperature and pressure, the value of specific heat capacity (Cp) is approximately 4.2 J/g°C. This implies that it takes 4.2 joules of energy to raise 1 gram of water by 1 degree Celsius.

2.what is translocation ??,give the chemical equation for translocation
plss help will mark brainlest..
Transpiration is a water balance process mediated by stomata opening. Translocation is the transport process of photosynthetic substances from leaves to other tissues.
What is transpiration?Transpiration is a water balance process.
Through stomata opening and closure (which depends on how hydrated the plant is) water vapor is expelled from the leaves.
If the plant is dehydrated, stomata close. If it is not dehydrated, it opens.By limiting water exit, stomata allow more water molecules to be available for light reaction processes when the plant is dehydrated.
The equation to calculate transpiration is as follows,
E = Gv (Cvs - Cva)
Where,
E is transpiration.Gv is the total vapor water conductance.Cvs is the water concentration inside the leave.Cva is the air water concentration.What is translocation?Translocation is a fast and dynamic process through which photosynthetic products are transported from the leaves to other tissues of the plant to be used or stored.
This transport is done by the phloem cells through active transport or osmosis (depending on the substance).
The translocation of elements from the leaves to the roots is fast.
In conclusion,
The chemical equation for transpiration is E = Gv (Cvs - Cva). Translocation is the movement of photosynthetic products from leaves to other plant tissues.You can learn more about translocation and transpiration at
