The process of fertilization involves the deposition of sperms into the vagina to the egg cell during sexual intercourse. Sperms make their way towards the cervix and uterus, and eventually goes to the fallopian tubes. <span>Only a few hundred will remain as they interact with the egg through the use of their heads and movement patterns.

</span><span>The process of implantation happens when the embryo, the fertimized eggs develops inside the fallopian tube after three days, and then travels to the uterus.</span>

HELP ASAP<br> Punnett Squares
pashok25 [27]

Answer: The genotype ratio of offsprings of a cross between one homozygous tall plant and one heterozygous tall plant is 2TT:2Tt

The phenotype ratio is that all offsprings will be tall.

The genotype ratio of a cross between two heterozygous red flowers is 1RR:2Rr:2rr. The phenotype ratio is 3 Red flowers: 1 white flower.

Explanation: From the information given, tall is dominant and short is recessive while red is dominant and white is recessive.

Let T represent the allele for tall height, t represent the allele for short height, R represent allele for red flowers and r represent allele for white flowers.

The genotype of a homozygous tall plant is TT, the genotype of a heterozygous tall plant is Tt, the genotype of a heterozygous red flowered plant is Rr.

The possible genotypes of offsprings of a cross between one homozygous tall plant and one heterozygous tall plant are TT and Tt.

Tt will manifest outwardly as tall because T is dominant over t. Therefore, all the offsprings will be tall.

The possible genotypes of a cross between two heterozygous red flowers are RR, Rr and rr. RR will manifest as red, Rr will also manifest as red because R is dominant to r while rr will manifest as white because white allele (r) is recessive. Therefore 3 plants will be red-flowered while 1 plant will be white flowered.

See the attached punnet squares for details of the cross.

The term describing bacteria with flagella that are arranged as a tuft coming from one pole is __________.
Masteriza [31]

Answer:

The correct answer is- Lophotrichous

Explanation:

There are four types of bacteria based on the presence and distribution of flagella on them. The bacteria which have only one flagellum at one pole that bacteria is called monotrichous.

The bacteria which have single flagella at both sides are called amphitrichous. Bacteria that have numerous flagella distributed evenly on their body surface are called Peritrichous.

The bacteria which have a tuft of flagella attached on one side or pole are called lophotrichous. Therefore the correct answer is lophotrichous.
