Answer:

b. nails instead of claws on their fingers and toes

Explanation:

Primates are a class of mammals in which humans are included. It is a very varied group, ranging from 30 gram lemurs to over 200 kg gorillas.

This group of animals is characterized, among other things, by having five fingers at its ends. They have clavicle, binocular vision, orbits surrounded by bone, etc. The vast majority have nails instead of claws, opposing thumb and vision that captures all colors.

Unfortunately, it is a very threatened order, as 60% of the world's primates could disappear within 25 years. This is all the fault of one species: the human.

Place the following steps of endomembrane system function in the correct order.

maks197457 [2]

Answer:

Explanation:

The correct option here would be D.

The endomembrane system refers to a group of membrane-based organelles whose primary function is to synergistically work together to modify, package, and transport lipids and proteins. The system includes organelles such as the lysosome, the nuclear envelope, the endoplasmic reticulum, and the Golgi apparatus.

For an endomembrane system function involving a protein, the protein would first of all need to be synthesized by the ribosome - the free ones or the ones attached to the rough endoplasmic reticulum. Thereafter, the synthesized protein would then be folded or packaged into transportable vesicles. The vesicles are then received by the Golgi apparatus which further modifies the proteins before transporting them accordingly.

Hence, the correct order of a typical endomembrane system function would be:

Ribosomes on the RER synthesize proteins.
Proteins are packaged into transport vesicles.
Golgi apparatus receives transport vesicles from the RER.
Proteins are modified by the Golgi apparatus.
Modified proteins may be secreted from the cell by exocytosis.

Answer:

a. Determine the allele frequencies of:

f(T) = 0.485 ≅ 0.48

f(t) = 0.515 ≅ 0.52

b. Determine the genotype frequencies of the exposed generation

F (TT) = 0.21
F (Tt) = 0.55
F (tt) = 0.24

the genotype frequencies of the next generation

F(TT) = 0.23
F(Tt) = 0.5
F(tt) = 0.27

Creating a prototype and troubleshooting are steps in the development of

MissTica

One of the essential early steps in the inventing process is creating a prototype--which, simply defined, is a three-dimensional version of your vision. Creating a prototype can also be one of the most fun and rewarding steps you'll take. That's because developing a prototype gives you the opportunity to really tap into your creativity, using those skills that inspired your invention idea in the first place. And whether you're making your prototype at home or hiring the services of an engineer, seamstress or machinist, it's truly exciting to see your idea transformed into something tangible and real.
