Answer:Sexual reproduction allows them to produce fit offspring that can survive under stressed environmental condition

Explanation:Reproducing sexually and asexually allows fungi to adjust as per the environmental condition.

When the conditions are favorable, they reproduce asexually and increase their number but when the condition are not favorable and environmental selective pressure occur then they undergo genetic variation through sexual reproduction to produce a stable and fit offspring that could survive under stressed condition with limited resources.

Asexual reproduction Since there are plenty of resources, the plant will want to reproduce quickly and colonize the area

3. Pansies can grow to be tall (T), which is dominant, or short (t), which is recessive. They can also be red (R),

Vilka [71]

Answer:

Pansy 1 Genotype: TtRr

Pansy 2 Genotype: ttrr

Pansy 1 Gametes: TR, Tr, tR, tr

Pansy 2 Gametes: All tr

Phenotypic ratio of offspring: 1:1:1:1 (1 Tall red: 1 Tall white: 1 Short Red: 1 short white)

Explanation:

This is a cross involving two different genes; one coding for height and the other for colour in pansies. The allele for Tallness (T) is dominant over the allele for shortness (t) in the first gene while the allele for red color (R) is dominant over the allele for white color (r) in the second gene.

According to the question, a pansy

that is heterozygous for both traits will have a genotype: TtRr while a pansy that is homozygous recessive for both traits will have a genotype: ttrr

In a cross between a TtRr and ttrr, the following allelic combinations of gametes will be produced by each pansy;

TtRr- TR, Tr, tR and tr

ttrr- tr, tr, tr, tr

Using these gametes in a punnet square (see attached image), a phenotypic ratio 1:1:1:1 consisting of (4 Tall red: 4 Tall white: 4 Short Red: 4 short white) offsprings will be produced.

Describe the muscle feature that is being used in each naming scenario. for example, you have probably figured out that trapeziu

maw [93]

1.Gluteus maximus and Gluteus minimus

This muscles are classified by their size. Maximus means the largest of the group, which is correct because the others are small and medium sized). Gluteus minimus is the smallest of the group.

2.Frontalis and Temporalis

The frontalis and the temporalis muscles are classified by their location. Frontalis is front of the frontal bone of the skull; It serves for facial expressions, raising eybrows.

Temporalis is located on top of the temporal bone of the skull; Is able to move the tmandible.

3. Orbicularis Oculi and Transverse abdominis:

These muscles are far away from each other but they were named based on the same feature: the direction of fibers.

Orbicularis is because their fibers form a circle.
Transverse because crosses or 'traverses' the abdomen

4.Flexor Carpi Ulnaris and Extensor digitorum longus

These muscles are classified by what they do- their action.

Flexor carpi ulnaris flexes the hand at the wrist while the extensor digitorium longus extends the foot and toes upward.

5. Sternocleidomastoid and Brachioradialis

These muscles are named based on their origin and insertion.

Sternocleidomastoid has two origins, one in the sternum and the other in the collare bone (clavicle). It's insertions is in the mastoid process of the temporal bone.

Brachioradialis has an origin on the brachium of the humerus and it's insertion is on the radius.

6. Biceps Brachii and Triceps Brachii

These muscles, with opposite functions, are named based on their number of origins.

Biceps brachii has two origins on the scapula that join to form a single muscle which is attached to the forearm

Triceps brachii has three origins on the humerus and joint to form one single muscle that attaches to the ulna.
