How do complement proteins differ from antibodies?

Biology
1 answer:
Pie4 years ago
5 0
Complementary proteins increase the efficiency of the antibodies. The antibodies bind to the foreign materials called as antigens. Complementary proteins do not do so. Rather, they act on the antibody-antigen complex and activated by the complex. They act up on the same and leads to the killing of the antigen. They are produced in the liver and antibodies are produced by WBCs.

In chickens, Black feathers (B) are dominant over white feathers (b). Complete the Punnett
PolarNik [594]

Answer:

(attached Punnett square below)

100% of the offspring will have black feathers

0% of the offspring will have white feathers

Explanation:

All the possible offspring have the genotype Bb, and since B (black) is dominant it will be the phenotype regardless of the presence of a b allele.

Therefore, all the offspring will be black (100%) and since none of the genotypes are bb there's no chance for white feathered chickens (0%)

hope this helps!

Compare and contrast prophase of mitosis and prophase of meiosis1?​
Crazy boy [7]

Answer:  

The homologous chromosomes pair together in prophase 1 of meiosis, but they do not during prophase 1 of mitosis. This is achieved by a process known as synapsis, where the similar chromosomes pair according to sequence similarity. The homologous chromosomes are held together by a protein structure known as the synaptonemal complex in a chromosome body known as a tetrad (because it contains 4 replicated chromosomes known as chromatids) or bivalent (if the organism is diploid). This pairing during prophase 1 of meiosis allows recombination to take place between the homologous chromosomes. This occurs early during prophase but the manifestation of recombination only becomes visible during the later stages of prophase 1 and in metaphase 1. Because the chromosomes adopt different structures during prophase 1 of meiosis, this stage is sub-divided into 5 stages: leptotene, zygotene, packytene, diplotene and diakinesis. It is during diplotene and diakinesis that the physical manifestation of recombination can be seen. This is the presence of chiasmata (chiasma, singular). These are the sites where recombination, or exchanges between homologous chromosomes, has taken place. By the end of prophase 1, it is only the chiasmata that holds the homologous chromosomes together. This constriction make the tetrads adopt a variety of structures, the shape of which depends upon the number of chiasmata formed. The tetrads stay in this conformation until metaphase 1. Synapsis, the formation of the synaptonemal complex, the formation of chiasmata does not take place during prophase 1 of mitosis and these processes represent the major differences between prophase of the two nuclear divisions.

Four friends were arguing about the flow of energy between organisms in a food chain. They
Bezzdna [24]

Answer:

I would agree more with Amos' opinion, thinking that most of the plant's energy ends up in the grasshopper.

Explanation:

In food chains, the flow of energy that occurs from one organism to another, from the producer to the tertiary or quaternary consumer. The amount of energy that can be transferred from one level to another is only 10%, with herbivorous animals taking up more of the energy that a producer has.

According to this, <em>it is logical to think like Amos, since the grasshopper -a primary or herbivorous consumer- will take advantage of more energy contained in the plant, with respect to the consumers of the higher levels</em>.
