Answer:
Yes.
Explanation:
Yes, all life on Earth depends on sunlight for obtaining energy and also shares a common ancestor of all organisms that lives on the land surface or in the oceans. Sun is the major source of energy through which plants produces food for itself and for other organisms. All the organisms have common ancestors which evolved with the passage of time when the change occurs in the environment and is responsible for the diversity of organisms.
which of the following is an object used in relative dating.

How could an error during transcription affect the protein that is produced
Answer:
The protein might be unable to function if an error during transcription occurs. Explanation: During transcription, the mRNA is formed. If the error encountered in the transcription, mRNA formed would be a transient one and would eventually get degraded.

Answer:
Rosalind Franklin and Maurice Wilkins used x-ray diffraction to create images of DNA, which Watson and Francis Crick used to create the double helix model.
heat is produced by radiant energy (A) when it travels through space (B) when it strikes matter (C) when its reflected from the Earth's surface (D) in all these ways
Answer:
Most of the solar radiation is absorbed by the atmosphere and much of what reaches the earth's surface is radiated back into the atmosphere to become heat energy. Dark colored objects, such as asphalt, absorb radiant energy faster than light colored objects.

biology question on enzymes
Answer:
D
Explanation:
because it have a shape like that and the optimum temperature is at 37 ish which Is right the other are not right.
Answer:
Option D
Explanation:
Because the max reaction rate of a majority of enzymes in homeotherms is about 40 degrees C, they will start to denature at higher temperatures. Of course enzyme activity will vary compared to other organisms, i think with these options that option D is your best bet.

There have been cases in history where a king divorced his queen because she produced only daughters. Using your knowledge of genetics, explain why this was an incorrect move.
Answer:
A child's gender (male or female) is determined by the chromosome that the male parent contributes.
Explanation:
Females have XX sex chromosomes. Males have XY sex chromosomes. A male infant results if the male contributes his Y chromosome while a female infant results if he contributes his X chromosome. Therefore, it is actually the King's fault that he is only producing female heirs.
The gender of a child is determined by the s ex chromosomes present in male and not by the female.
What are s ex chromosomes?Humans have 23 pairs of chromosomes. 22 of these pairs are called autosomes and are same in both male and female.The 23rd pair chromosome is different in male and female and are called s ex chromosomes because determines the s ex of a child.The female has two copies of X chromosomes whereas males has one X and one Y chromosome.During fertilization, the embryo receives one set of chromosomes from each parents.Child with XX chromosomes will be girl and child with XY chromosome will be boy.As, the mother can only give X chromosome then the gender of child is determined by the chromosomes he received from his father as it has both X an Y chromosomes.
Hence, the female should not be blamed if she gives birth to only daughters.

Answer:
C. Directional selection
Explanation:
The graph given shows that an extreme phenotype is favoured as allele frequency shifts towards the direction of the phenotype. Thus, due to the natural selection that occured as a result of draught, an extreme trait which is a particular beak size of the birds is favoured over others.
One phenotype is selected over the other in one direction. This is an example of directional selection, which occurs when one trait at the end of a spectrum is selected for against the others that have less fitness.
describe the connection between the digestive and respiratory systems
Answer:
Explanation:The respiratory system brings oxygen into the lungs when you breathe. The digestive system breaks food down into nutrients such as glucose. Now the circulatory system enters the picture. It transports glucose and other nutrients from the digestive system to the cells.

what two gases are being attributed with global climate change?
Answer:
Indeed, carbon dioxide, a byproduct of fossil fuel combustion, is the principal greenhouse gas contributing to global warming. However, other greenhouse gases including methane, nitrous oxide, and a number of industrial-process gases also are important contributors to climate change.
Barrera que delimita a la celula y que contiene sus organelos y los productos generados dentro de la misma , a traves de ella entran nutrientes y expulsan desechos
Answer:
Membrana celular
Explanation:
La membrana plasmática o membrana celular, presente en todas la céluas, la protege y encierra a distintas organelas, que al estar aisladas deñexterior, funcionan como una unidad difereciada. Aun asi, cada célula mantiene comunicación con otras células a partir de esta membrana. Esta estructura, a parte, permite el paso de sustancias desde y hacia el iterior celular. Moleculas necesarias para el adecuado funcionamiento de la celula ingresan a la misma, mientras que otras destinadas a exportación, desechos, mentenimiento del equilibrio, etc, salen al espacio intercelular. Las membranas biológicas estan formadas por una bicapa lipídica. los lípidos se posicionan de manera tal que las cabezas hidrofilicas apuntan hacia el exterio e interior celular, mientras que las colas hidrofóbicas se disponen hacia el interior de la bicapa. Las membranas celulares son fluidas, es decir que las moleculas que la componen tienen la capacidad de moverse.
Dentro de la célula, e incluidas en el citoplasma, hay varias organelas que también se encuentran delimitadas por membrana, tales como nucleo, reticulo endoplasmático, aparato de golgi, mitocondrias, cloroplastos, vacuolas y vesiculas. El contenido de estas organelas se encuentra aislado del citoplasma gracias a la contención de la membra.
The human chromosome 1 is approximately 250 million nucleotides long. In order to reveal the sequence of human chromosome 1, the chromosome is broken up into hundreds of fragments. These fragments are then pieced together in the correct order to generate the long, continuous sequence of nucleotides in the chromosome, a process referred to as:
Answer:
The process is termed as sequence assembly.
Explanation:
The aligning and merging fragments from a longer sequence of DNA so that the original sequence can be redeveloped is termed sequence assembly in bioinformatics. The process of sequence assembly is essential as the DNA sequence technology fails to read the complete sequence of genomes in one go, and apart from that, it reads small fragments of DNA sequences between the sizes of 20 to 30000 base pairs.

The allele combinations are?
O genetics
O mitosis
O genotype

Answer:
genotype
Explanation:
Within an individual organism, the specific combination of alleles for a gene is known as the genotype of the organism, and (as mentioned above) the physical trait associated with that genotype is called the phenotype of the organism.
The invention of the microscope led to the discovery of the cell by Robert Hooke. While looking at cork, Hooke observed the box-shaped structures, which he called "cells" because they reminded him of the cells (rooms) found in monasteries. This discovery led to the development of the cell theory. Credit for developing the cell theory is usually given to two scientists. Theodor Schwann and Matthias Schleiden. The cell theory was then proposed by Theodor Schwann in 1839. There are three parts to this theory: living organisms are made up of cells, cells are the basic structural unit of all organisms, and all cells come from pre-existing cells. Which of these is supported by the tenets of the cell theory? Select ALL that apply. les )) A) Energy flow occurs within cells. B) Mitosis produces identical daughter cells. C) Living organisms can be unicellular or multicellular. D) DNA is copied and passed between cells during cell division. E) Single-celled bacteria grow and then divide in half to make new bacteria.
Living organisms are made up of cells, cells are the structural unit of all organisms, cells come from pre-existing cells Energy flow occurs within cells.
What are the main points of cell theory?The main points of cell theory are:
All living things are made up of cells.Cells are the raw building blocks of life.All cells come from preexisting cells through the cycle of cell division.Energy flow occurs within cells.Thus, cells come from pre-existing cells Energy flow occurs within cells.
