Cattle egrets hitch a ride on domestic cows and eat insects that are stirred up by their activity. What term describes this rela

Serhud [2]2 years ago

Ans.

Biological  interactions include different types of interactions between organisms that reside together in a community.

Cattle egrets show interaction with domestic cows and feed on the insects present in them. The cattle egrets get food from the cows, while there is no benefit or harm to the cows. This type of biological relationship is known as commensalism, in which one organism, out of interacting organisms, get benefit, while other organism neither harmed or benefit.  

Thus, the term that describes this relationship is 'commensalism.'

Suppose virus A has a viral genome of 19,000 bp, and 10,000,000,000 viruses are replicated in an infected individual in a single
Kitty [74]

Answer:

1 day.

Explanation:

From the given information:

The rate of mutation induced by RNA polymerase is:

\implies \dfrac{1}{10000}= 0.0001

Since the genome comprise of 19000 bp;

To complete a single replication, the viral cycle induce: = \dfrac{19000}{1000}

= 1.9 \ mutation \\ \\  \simeq 2 \  mutation

However, in a single day; 10,000,000,000 viruses are reported to be replicated.

Hence, if a virus has 2 mutations; Then 10,000,000,000 virus will have:

= \dfrac{10,000,000,000}{2} \\ \\ = \text{5000000000 \ mutations \ in \ a \ half \ day which is half} \\ \\ \text{ the given no of the replicated virus}

SO, to round this up to whole number, it will take 1 day (s) to overcome the therapy.

Systematists have used a wide variety of traits to reconstruct the phylogenies of particular groups of organisms. Which one of t
Effectus [21]

Answer:

5. all of the above traits combined

Explanation:

Phylogeny has to do with the study of evolutionary relationships among living organisms based on the premise of the theory of organic evolution that states that all living organisms came from a common ancestor.

Phylogeny incorporates molecular, morphological, anatomical, biochemical and behavioural traits in order to arrive at a phylogenetic tree that represents ancestral lineages.

<em>Hence, the correct option is option 5. </em>

STatiana [176]
<h3><u>Answer and explanation;</u></h3>

<u>Binary Fission. </u>

  • <em><u>Binary division is a process of cell division in which an organism replicates itself together with its DNA, then divides into two identical organisms.</u></em>
  • <em><u>Binary fusion is a type of asexual reproduction by separation of the body of n organism into two bodies</u></em>. Organism duplicates its genetic material also known as the DNA, and then divides into two parts, with each new organism receiving a copy of DNA.

What did rosenberg and trevathan discover in their study comparing human and nonhuman primate birth?
melamori03 [73]
When comparing the birth patterns of humans and non-human primate, Rosenberg and Trevathan discovered some very clear differences:

1. The human period of labour and child birth is exceptionally long and painful compared to other non-human primates.
E.g. a human labour can last anywhere from 10-20 hours while that of a chimpanzee lasts only 2 hours.

2. Humans have the ability to walk straight, the trade off however is that it is extremely difficult and painful to give birth to a big brained human baby.
