The four main types of pest

Biology
1 answer:
-Dominant- [34]3 years ago
4 0

Answer:

1) Insect

2) Mites

3) Rodents

4) Animals

5) Birds

Explanation:

1)  These are significant and significant pests. Insects have three pairs of legs, two pairs of wings, a segmented body, and complex eyes and antennae that are unique to them. Insects are smart, extracting sap from plants, biting plant parts, burrowing into fruits, twigs, and leaves, attacking roots, barks, and blooms, among other things. Larvae, adults, and nymphs are the stages of insect pests that cause harm.

2) These are insect-like organisms with a soft body and four pairs of legs. The colour of these small organisms is red or pastel yellow. They feed on the plant's sap and attack the crops in large numbers.

3) This bug consumes a considerable amount of human food and causes widespread crop damage. They're also to blame for massive grain losses on fields, in warehouses, and in homes.

4) Wild boars, deer, elephants, buffalo, jackals, monkeys, and squirrels are among the animals that inflict direct harm to agricultural plants. They devour the plants and, as a result, squander a tremendous amount of food.

5) Birds devour grains and destroy crop plants. Crows, parrots, and sparrows are among the most common birds that prey on crops.

(Hope this helps can I pls have brainlist (crown)☺️)

In guinea pigs hair straightness or curliness is thought to be governed by a single pair of alleles showing incomplete dominance
Nimfa-mama [501]

Answer:

Frequency of allele S is p = 0.4939

Frequency of allele C is q = 0.666

The population is not in Hardy-Weinberg equilibrium

Explanation:

Given -

Number of individuals with straight hair = 244

Number of individuals with curly hair = 444

Number of individuals with Wavy hair = 312

Let "p" represents the frequency for allele for straight hair and "q" represents the frequency for allele for curly hair

p^2 represents the frequency of genotype "SS"

p^{2} = \frac{244}{1000} \\= 0.244

q^2 represents the frequency of genotype "CC"

p^{2} = \frac{444}{1000} \\= 0.444

2pq represents the frequency of genotype "SC"

2pq = \frac{312}{1000} \\= 0.312

Frequency of allele S is p

= \sqrt{0.244} \\= 0.4939

Frequency of allele C is q

tex]= \sqrt{0.444} \\= 0.666[/tex]

For being in Hardy Weinberg's equation-

p+q=1\\

Substituting the values in above equation, we get -

0.4939+0.666\neq 1

hence, the population is not in Hardy-Weinberg equilibrium

In Meiosis 1 in the prophase exactly is there duplicated chromosomes?
MArishka [77]

Answer:

please give me brainlist and follow

Explanation:

During prophase I, the chromosomes condense and become visible inside the nucleus. Because each chromosome was duplicated during the S phase that occurred just before prophase I, each now consists of two sister chromatids joined at the centromere. This arrangement means that each chromosome has the shape of an X.
