Why where the Galapagos Turtles different from the mainland turtles if they shared a common ancestor?​

Answers

Answer 1
Speciation! Speciation occurs when a single species becomes two or more separate populations by a geographical barrier. This changes each population’s environment which forces them to adapt. Eventually these populations will become so different from each other that they will not be able to interbreed populations and create fertile offspring. This is what makes them different species, but they still share a common ancestor.

Answer:

A) Dirt

Explanation:

Our environment comprises of two factors namely biotic factors and abiotic factors. Biotic factors are those in an ecosystem that consists of all living organisms such as plants, trees, humans, insects, animals, birds, etc. These living organisms will interact with each other and sustain their life.  

Abiotic factors are those that contain non-living organisms. These factors include soil, air, water, sunlight, etc. These factors often have a greater impact on biotic factors. From the question, a plant is a living thing and it belongs to the biotic factor.

1. The materials are physically combined because all of the materials including the sand, salt, and iron fillings are their own substances and they maintain their original form. This is a mixture and they aren't chemically combined.

2. To separate each of the materials physical means would be used because since they're their own individual substances and have kept their original form they're mixed and not chemically combined.

3. The iron and oxygen atoms in rust are chemically combined because they are no longer individual substances and haven't kept their original form, so therefore they're a chemical combination.

Why do large islands usually have more species than smaller islands?

Answers

Answer: Reason Why

Explanation: A bigger target is easier to hit than a small one, and a big island is more likely to have species land on it by chance than a small one is. Larger islands have more space than smaller islands, so there are likely to be more resources available for species to use. The opposite is true for smaller islands.

Like replication and transcription, translation is a process in which the information present within a nucleic acid template is used to guide the synthesis of a new polymer. But the translation machinery is much more complex than the machinery involved in replication or transcription. Discuss the aspects of translation that make it so challenging for the cell.

Answers

Answer:

The aspect of translation that makes it so challenging for the cell is that it involves too many steps and too many molecules and organelles. mRNA associated with rRNA and tRNA. rRNA reading mRNA in a specific direction. Codon sequences indicating where to start and where to finish the synthesis. Different codons codifying for different aminoacids and tRNA recognizing those codons to add the correct amino acid to the chain. If the protein is destined to exportation, RER and Golgi complex are also involved in the process.  

Explanation:

In protein synthesis, the first step is to synthesize messenger RNA, mRNA. The transcription is the coping process of the DNA section, and it happens in the nucleus. After that, the translation occurs when the formed mRNA moves to the cytoplasm through the nucleus membrane pores.

Once in the cytoplasm, it begins the translation process. mRNA meets a free ribosome, which is the primary structure for protein synthesis. Ribosomes are composed of two subunits, a big one and a small one. They also associate with different tRNA that carrying amino acids. Ribosomes might be floating freely in the cytoplasm or can be attached to the rough endoplasmic reticulum.

The ribosome reads mRNA in the 5´ to 3´ direction, and, according to the codons that are being readen, tRNA transfers the correct amino acids to build the polypeptide chain. Each tRNA has two important sites. One of them that couples with the codon of the mRNA molecule, named anticodon. The other site couples with an amino acid through the action of the aminoacyl-tRNA synthase enzyme. The whole complex, amino acid + enzyme + tRNA is named aminoacyl-tRNA. Considering that there are twenty amino acids available, there are also twenty complexes of aminoacyl-tRNA, one for each amino acid.  tRNA allows amino acids to align according to the nucleotidic sequence in the mRNA molecule.  

Once the new amino acid links to the growing peptidic chain, the binding between the amino acid and the tRNA molecule breaks. The tRNA is now free to join another amino acid and repeat the cycle.  

The protein is synthesized from the amino terminus to the carboxy terminus, while the added amino acids to the chain are coded by a codon formed by three bases in the mRNA. mARNs also have a start and end codon that are the signals of the synthesis initiation and finish. When the ribosome reaches the end codon, protein synthesis is over.

And if the protein is destined for exportation or cell membrane, its synthesis also involved organelles like the Rough endoplasmic reticulum and the Golgi complex.

Which of the following correctly states how genes, chromosomes and traits are related? A Chromosomes are part of genes. The traits determine our chromosomes. B Traits are segments of chromosomes. The chromosomes make up our genes. C Genes are segments of DNA on chromosomes. The genes code for proteins that make our traits. D Chromosome are make up of DNA which is divided into genes. The traits are all of the chromosomes we find in a cell.

Answers

Answer:

C

Explanation:

While D could be the right answer if it was phrased better the most liekly answer seems to be C as Genes are small segments of DNA and DNA makes up chromosomes in turn causing chromosomes to be made up of genes. I believe that proteins do make our traits so C is the best answer.

Genes are segments of DNA on chromosomes. The genes code for proteins that make our traits. So, the correct option is (C).

What are Genes?

Genes are defined as the basic units of heredity passed from parent to child that are made up of sequences of DNA and arranged one after the other at specific locations on chromosomes in the nucleus of cells.

Genes are found in each one of the 37 trillion cells that make up the body. Every cell has a nucleus and inside each nucleus are chromosomes and all chromosomes are made of DNA, molecules that contain genetic information called genes.

A chromosome contains hundreds to thousands of genes where each normal human cell has 23 pairs of chromosomes, for a total of 46 chromosomes. Trait is any gene-determined characteristic and is often determined by more than one gene.

Thus, Genes are segments of DNA on chromosomes. The genes code for proteins that make our traits. So, the correct option is (C).

9. Which nucleus has role in conjugation in Paramecium
a) Mega nucleus
b) Micronucleus
c) Macronucleus
d) Cellular nucleus​

Answers

( b ) Micronucleus has role in conjugation in paramecium.

The organism's germ line genetic material is kept in the micronucleus. It is in charge of the genetic rearrangement that takes place during conjugation and generates the macronucleus (cross-fertilization). Thus option B is correct.

What Micronucleus role in conjugation in Paramecium?

The pairing and subsequent fusion of two paramecia is a process known as conjugation. It is known as a cytoplasmic bridge where they converge. After meiosis, the diploid micronucleus divides into four new micronuclei. The micronuclei of the cell, all except one, break down.

This method doesn't include meiosis or nuclear fusion. It manifests in a single person in the manner described below: Macronucleus deteriorates and vanishes. Eight nuclei are produced after the two micronuclei divide twice through mitosis.

Therefore, Micronucleus has a role in conjugation in Paramecium.

Answers

Answer:

The bird populations will decrease due to competition for resources such as food and nesting sites.

Explanation:

Ecological succession can be defined as the process by which the biological structure of a community, i.e., the group of interacting populations of species that occupy a particular area, changes over time. Human activities such as, for example, deforestation in order to develop an urban ecosystem, can dramatically alter the process of succession and literally destroy the natural balance of biological communities. In this case, it is expected that human activities have a negative impact on bird populations by increasing intra and interspecific competence with other organisms for limited resources (i.e., food and nesting sites).

Estimate the electric field in the membrane wall of a living cell. Assume the wall is 14 nmnm thick and has a potential of 0.11 VV across it.

Answers

Answer:

The electric field in the membrane wall of a living cell is 7.857 x 10⁶ V/m.

Explanation:

Given;

thickness of the membrane wall, d = 14 nm = 14 x 10⁻⁹ m

potential of the membrane wall, V = 0.11 V

The electric field in the membrane wall of a living cell is calculated as;

[tex]E = \frac{V}{d} \\\\E = \frac{0.11}{14 \times 10^{-9}} \\\\E = 7.857 \times 10^6 \ V/m[/tex]

Therefore, the electric field in the membrane wall of a living cell is 7.857 x 10⁶ V/m.
