Explique de qué manera la deriva continental ha influido en la distribución de especies vegetales y animales en el mundo.

Answers

Answer:

la deriva continental ha notablemente influido en la distribución actual de las especies. Este fenómeno se puede observar en grupos de organismos similares que se encuentran en diferentes continentes, lo cual concuerda con la idea de que la separación entre dichos continentes se produjo más tardíamente en el tiempo  

Explanation:

La teoría de la deriva continental plantea que durante el final del Paleozoico y el principio del Mesozoico (hace aproximadamente hace 225 millones de años) las masas continentales actuales se encontraban unidas formando una gran masa de tierra o supercontinente conocido como 'Pangea'. Esta teoría se basa en evidencia de diversa fuentes incluyendo pruebas geográficas (coincidencias en las costas de algunos continentes), paleontológicas (mismos fósiles en diferentes continentes), geológicas y tectónicas (por ej., la presencia de cadenas montañosas que se separaron hace millones de años), y paleoclimáticas (evidencia de climas similares durante el pasado en continentes diferentes). La deriva contiental afectó la distribución actual de especies de plantas y animales. Por ejemplo, la fauna en Europa es semejante a la observada en Norteamérica porque estos continentes se separaron más tardíamente en el tiempo que otros contientes/masas de tierra del hemisferio sur, y dichas semejanzas se encuentran reflejadas en organismos evolutivamente más relacionados (menor tiempo de divergencia evolutiva).

Two plants with an inated seed shape produced 340ospring. Of those 340, six ospring had a constricted pod shape. What are the genotypes of the parents?

Answers

Answer:

The genotype of both parents will be heterozygous for the trait, Ii.

Explanation:

Let us assume that the shape of the seeds is controlled by a single diallelic gene.

Dominant allele I expresses the inflated phenotypeRecessive allele i expresses the constricted phenotypeThe dominant phenotype is inflated seeds, expresses by genotype II and Ii. The dominant allele hides the expression of the recessive allele, so if the genotype has at least one dominant allele, the phenotype will be inflated. The recessive phenotype is constricted seeds, expressed by the genotype ii. In this genotype there is no dominant allele, so the recessive allele can be expressed.

The individual with constricted seeds must have two recessive alleles i in its genotype ⇒ ii.

One of the i alleles was inherited from one of the parental plants, while the other parental plant provided the other i allele. So both parental plants must carry the recessive allele in their genotype.

We know that both parental plants have inflated seeds, which is the dominant phenotype.  

So, if both parental plants have inflated seeds and also carry the recessive allele, then the parentals´ genotype must be heterozygous, Ii.

Both plants exhibit the dominant inflated phenotype but carry a recessive allele which will be provided to some of the descendants. These last individuals will have constricted seeds.

As carbon moves throughout earths systems how are different parts of the biosphere(the part occupied by living things) affected?

Answers

Answer:

Carbon is an essential factor to the survival of living things.

Explanation:

It is produced as a waste by-product of metabolism in living organisms and combines with oxygen to be released as Carbon Dioxide (CO2).

Plants on the other hand require CO2 to process sunlight and nutrients into energy. They in return release oxygen which is required by animals to break down food.

Factories, businesses, people (as they generate electricity, transport people and goods, etc) release lots of carbon into the atmosphere it also combines with oxygen again to form C02.

The ocean and water bodies also serve as a collecting conduit of CO2, especially where the water temperature is relatively warm. When CO2 is captured by the ocean, it is used by some sea animals to make shells.

Earth and Venus are about the same size. So, the correct option is (A).

What is Earth?

Earth is the third planet from the Sun and the only celestial object known to harbor life. Only Earth maintains liquid surface water in the Solar System. About 71% of Earth's surface is made up of ocean, which dwarfs Earth's polar ice caps, lakes, and rivers.

Earth consists of land, air, water and life where land consists of mountains, valleys and flat areas and air is composed of various gases, mainly nitrogen and oxygen. Water includes oceans, lakes, rivers, streams, rain, snow, and ice.

Venus is known as our sister planet because of the similarity in size, mass, density, and volume that both planets are believed to share a common origin at the same time from a condensed nebula about 4.5 billion years ago.

Thus, Earth and Venus are about the same size. So, the correct option is (A).

What Is the location of the instructions that code for traits?

Answers

Answer:

Traits are coded for in DNA, specifically in genes.

Explanation:

DNA, as you probably already know, is made up of long sequences of nucleotides of A's, T's, C's, and G's. When transcripted into mRNA and translated into proteins in ribosomes, the order of these nucleotides signal which amino acids to produce for the protein. Proteins are extremely important and have many roles throughout the body, which means they actualize the code of DNA into physical traits. I hope this helped.

Gametes (SEX CELLS) have ... A. half the number of chromosomes found in the body cells B. twice the number of chromosomes found in body cells C. two sets of chromosomes

Answers

Answer:

A. Half the number of chromosomes found in the body body cells

Explanation:

Somatic (body cells) have 2 sets of chromosomes, while gametes have 1 set of chromosomes. Sperm has one set, and an egg has one set allowing both to fuse to create a new organism.

Answer:

[tex]\boxed {\boxed {\sf A. \ Half \ the \ number \ of \ chromosomes \ found \ in \ the \ body \ cells}}[/tex]

Explanation:

Gametes are sex cells, such as the egg and sperm. They are used in sexual reproduction to produce offspring.

The sex cells are produced during meiosis. The DNA or genetic material is replicated, then the cells divide twice. After this, four haploid cells are produced with half of the genetic material. For example, human body cells have 46 chromosomes but sex cells have 23 chromosomes.

They contain half the genetic material for an important reason. During fertilization, an egg and a sperm fuse. Each one contributes half of the genetic material from the mother or father to create one complete set for the offspring.

Gametes have half the number of chromosomes in body cells and choice A is correct.

Which the following takes the most time?
Meiotic prophase II
Mitotic prophase II
Meiotic prophase I
Mitotic prophase I

Answers

Option D.

The time required then for the complete process of mitotic cell division would lie within the following limits: Prophase, 30 to 60 minutes; metaphase, 2 to 10 minutes; anaphase 2 to 3 minutes; telophase 3 to 12 minutes and the reconstruction period from 30 t'o 120 minutes: total 70 to 180 minutes.

Meiotic prophase I takes more time than other processes of mitosis or meiosis.

What are the phases of meiosis?

Meiosis is a type of reductional division as the chromosome number reduces to half in this type of division. It results in the formation of haploid cells. The process of meiosis takes place in germ cells and gives rise to gametes for sexual reproduction. Each process of meiosis produces four haploid cells.

Meiosis is categorized as meiosis I and meiosis II. Meiosis I gives rise to haploid cells. The prophase I of meiosis I have 5 further stages. These are leptotene, zygotene, pachytene, diplotene and diakinesis.

Meiosis II is comparatively simple and is very much like Mitotic division, except the cells undergoing division are the haploid cells produced by meiosis I. Hence, Meiotic prophase II also takes less time than Meiotic prophase I.

Therefore, the process that takes the most amount of time is the Meiotic prophase I.

   2- Amino acid sequence (5'3' Frame): Tyrosine-Cysteine-stop codon-Serine-Lysine-Lysine (abbreviation: YC-SKK)

Explanation:

Transcription is a cellular mechanism where a specific sequence of a DNA strand is used as template to synthesize an RNA molecule, often a messenger RNA (mRNA) molecule that is subsequently utilized to create an ordered sequence of amino acids (i.e., a protein) by a mechanism referred to as translation. In RNA, uracil (U) always replaces thymine (T) bases. During translation, the mRNA is "read" according to the genetic code which associates the DNA sequence to the amino acid sequence in the polypeptide chain. For such purpose, each triplet of nucleotides or 'codon' in the mRNA specifies one aminoacid or one-stop codon (stop codons are UAA, UAG, UGA).
