Explain why lamarckism is currently not a widely accepted theory​

Answers

Answer 1

Answer:

Its not really taught in schools that much.

Explanation:

Answer 2
Lamarck's theory cannot account for all the observations made about life on Earth. For instance, his theory implies that all organisms would gradually become complex, and simple organisms disappear.

Lamarck’s theory of evolution, also called as theory of inheritance of acquired characters was rejected since he suggested that the acquired character which an organisms gain through its life experiences are transferred to its next generation, which is not possible since acquired characters does not bring any change to an individual’s set of genes.

Which is NOT true of homologous chromosomes? *
(1 Point)

they have genes for the same traits
they are in pairs
they have genes that are in the same order

Answers

Answer:

Homologous chromosomes are NOT identical.

Explanation:

They contain slight differences in their genetic information, allowing each gamete to have a unique genetic makeup. Consider that the homologous chromosomes of a sexually reproducing organism are originally inherited as two separate sets, one from each parent.   Hope this helps :)

October 1, 2017 marks 27 years since the beginning of the Human Genome
Project. The goal of the group was to map the entire 3 billions bases and
80,000 genes in the human genome. On April 14, 2003, it was announced
that the goal was accomplished. Using this information, scientists have been
able to predict the risk of genetic diseases and understand the process of
inheritance. Which of the following statements best describes the process of
using the genetic code to produce polypeptides (proteins)?
Translation is used to produce a strand of RNA and proteins from a single strand of DNA.
O RNA produces a strand of DNA through transcription, then the DNA builds a protein molecule
through translation
O A single strand of DNA is used to make mRNA using translation, then the mRNA provides the
template for producing a protein through transcription
O A single strand of DNA is used to produce mRNA through transcription, then translation provides
the code for bonding amino acids to make a protein.

Answers

Answer:

The last one. A single strand of DNA is used to produce mRNA through transcription, then translation provides the code for bonding amino acids to make a protein.

Explanation:

Educated guess, but also. Translation is the process by which mRNA is decoded and translated to produce a polypeptide sequence, otherwise known as a protein. This method of synthesizing proteins is directed by the mRNA and accomplished with the help of a ribosome, a large complex of ribosomal RNAs (rRNAs) and proteins.

Calculate the molarity of 0.75 L of a solution containing 0.83 g of dissolved KCI. A 0.015 M B 0.75 M C 1.1 M D 6.2​

Answers

Answer:

A 0.015M

Explanation:

Molarity, which refers to the molar concentration of a solution, can be calculated using the formula:

Molarity (M) = mole (n) / volume (L)

Based on the information provided in this question, the solution contains 0.83 g of dissolved KCI.

We can calculate the number of moles of KCl in the solution by using the formula:

Mole = mass ÷ molar mass

Where atomic mass of; K = 39, Cl = 35.5

Molar Mass of KCl = 39 + 35.5

= 74.5g/mol.

Mole = 0.83g/74.5g/mol.

mole = 0.01114

Approximately, n = 0.011mol

Hence, molarity = 0.011mol/0.75L

Molarity = 0.0146

Molarity = 0.015M

.. Which pair of organisms is most likely to have adaptations in common?

Answers

Answer: the 1st one

Explanation:

A grassland predator and prey, such as a cheetah and a zebra. Therefore correct option is (A).

What organisms have common adaptations?

The pair of organisms that is most likely to have adaptations in common is a pair of organisms that share similar environmental pressures or ecological niches. Organisms that occupy similar habitats, have similar diets, or face similar challenges are more likely to evolve similar adaptations over time.

For example, predatory animals such as lions, tigers, and leopards have evolved similar adaptations such as sharp claws, powerful jaws, and keen senses to help them catch prey. Similarly, desert-dwelling animals such as camels, kangaroo rats, and fennec foxes have adaptations such as the ability to conserve water, tolerate heat, and dig burrows in sandy soil to survive in their arid environments.

What is your opinion on the use of stem cells, obtained from fertilized eggs or early stage embryos

Answers

I believe that it can help in the future. Who knows embryonic stem cells may lead to new, and more effective treatments for serious human ailments and alleviate the suffering of thousands of people!

USE OF STEM CELL:

The first attempts to turn mature cells back into pluripotent stem cells involved a process called cloning. In the cloning process, an egg is fertilized in the lab, and right after fertilization, the DNA is removed from the egg.These stem cells come from embryos that are three to five days old. These are pluripotent (ploo-RIP-uh-tunt) stem cells, meaning they can divide into more stem cells or can become any type of cell in the body. This versatility allows embryonic stem cells to be used to regenerate or repair diseased tissue and organs.Despite the potential benefit of using human ES cells in the treatment of disease, their use remains controversial because of their derivation from early embryos.
