All of the following are true of red blood cells except that they are a spherical shape  

The most typical produced element is the erythrocyte, also called a red blood cell (or RBC): There are millions of erythrocytes in a single drop of blood but only a few thousand leukocytes. Males and females have roughly 5.4 million and 4.8 million erythrocytes per microliter (L) of blood, respectively they are bi concave disc shaped. In actuality, erythrocytes are thought to account for around 25% of all body cells. They are quite tiny cells, as one might expect, with a mean diameter of only 7-8 micrometers (m) (Figure 1). The main jobs of erythrocytes are to transport the breathed oxygen from the lungs to the body's tissues and to collect up some of the waste carbon dioxide (approximately 24 percent).

Looking at the image, A would be DNA, B would be the cell membrane, C would be the ribosome, while D would be the cytoplasm.

They are the functional components of a cell.

Cell organelles vary according to cells, however, there are some organelles that are common to all cells irrespective of their origin.

These organelles include the cell or plasma membrane, the DNA, the cytoplasm, and the ribosome.

The plasma membrane delimits the cell's interior from the exterior and acts as a semi-permeable interface to materials.

The DNA stores the genetic information of cells. The cytoplasm represents the liquid interior of the cell, while the ribosome is the site of protein synthesis for all cells.

Despite his lack of knowledge, he observed that all possible combinations of factors can occur in the gametes leading to great variation in the genetic makeup of the eggs and sperm created.

Based on the mention of "factors" and "variation in the genetic makeup of the eggs and sperm," it can be inferred that the sentence is likely referring to the process of meiosis, which is the type of cell division that produces haploid cells (gametes) with half the number of chromosomes as the original cell.

During meiosis, homologous chromosomes pair up and exchange genetic information through a process called crossing over, which creates new combinations of alleles on the chromosomes.

Additionally, during the second division of meiosis, the sister chromatids of each chromosome separate, resulting in further variation in the genetic makeup of the resulting gametes.

Overall, meiosis is a key process in sexual reproduction that generates genetic diversity among offspring.

Answer:

continental drift

Explanation:

The most likely reason for this would be continental drift. It is believed that millions of years ago our world was one giant continent. This continent began breaking apart and drifting slowly more and more as millions of years passed by, ultimately creating the seven continents we know now. This would mean that Brazil and South Africa were most likely once the exact same location or the edge of where the continent broke apart. This would explain why the same rock was found in both locations.

Answer:

Enzymes and catalysts both affect the rate of a reaction. In fact, all known enzymes are catalysts, but not all catalysts are enzymes. The difference between catalysts and enzymes is that enzymes are largely organic in nature and are bio-catalysts, while non-enzymatic catalysts can be inorganic compounds

Explanation:

All known enzymes are catalysts, but not all catalysts are enzymes

Catalysts are substances that increase or decrease the rate of a chemical reaction but remain unchanged. Enzymes are proteins that increase rate of chemical reactions converting substrate into product.

The mass of a 235 92U nucleus is less than the sum of the masses of a 141 56Ba nucleus, a 9236Kr nucleus, and two neutrons, all separated from each other.

The mass of the nucleus is affected by the number of protons and neutrons it contains. The total mass of a nucleus is determined by adding up the masses of the individual protons and neutrons. The mass of a 235 92U nucleus is less than the sum of the masses of a 141 56Ba nucleus, a 9236Kr nucleus, and two neutrons, all separated from each other.The mass of the nucleus is less than the sum of its parts due to a phenomenon known as nuclear binding energy.

The energy required to break a nucleus down into its individual protons and neutrons is referred to as nuclear binding energy. When a nucleus is created, nuclear binding energy is released, which lowers the overall mass of the nucleus by a small amount.The amount of nuclear binding energy present in a nucleus is determined by the number of protons and neutrons it contains. The larger the number of protons and neutrons, the greater the amount of nuclear binding energy. The nucleus becomes more tightly bound as a result of the increased nuclear binding energy, and its overall mass is reduced slightly.

Answer:

Transcription is unidirectional because you are copying only ONE side of the DNA. Remember that DNA is a double stranded helical structure. One strand of DNA is complementary to the other strand.

Explanation:

The sequence of RNA codons resulting from the substitution mutation that changed the 5th base in the DNA from a C to a T is AUGUGCGUUAUCCAGGGUAGCCAAUUGA.

In DNA, the base C (cytosine) pairs with G (guanine), while in RNA, the base C pairs with G. However, due to the substitution mutation, the original C is replaced by a T (thymine) in the DNA sequence.

In RNA, thymine is replaced by uracil (U). Therefore, the RNA codons corresponding to the mutated DNA sequence can be derived by replacing each T with U and maintaining the sequence order.

The original DNA sequence TACACGCAATTACCAGGGTAGCCATTGATT would have the corresponding RNA codons AUGUGCGUUAUCCAGGGUAGCCAAUUGA. Each codon consists of three bases and represents a specific amino acid or a start or stop signal in the translation process of protein synthesis.

Explanation:

This biome's soil is fertilized and it is rich because of the decay of deep.

(I hope this make sense)

Answer:

Explanation:

Secondary succession usually occurs faster than primary succession because the substrate is already present. In primary succession, there is no soil and it needs to form. This process takes time, as pioneer species must colonize the area, they must die, and as this happens over and over again, soil forms.

The simplest approach to tell if a once adaptive characteristic has been lost several times is to evaluate the quantity of genetic input and environmental impact that define the range of phenotypes seen in the trait. Option 2 is Correct.

Once-useful features can become obsolete and even disappear when organisms adapt to a particular habitat and way of existence (such as the ability to synthesize ascorbic acid). The development of whales' smaller hind limbs is a well-known example.

These is closely related two creatures are may be inferred from similarities and differences between "identical" genes (i.e., a pair of homologous genes) in those animals.

All of the DNA molecules would move to the top of the gel if DNA was loaded at the bottom of a gel but the positive and negative poles were accidentally switched. So option A is the right answer.

DNA fragments of different lengths can be distinguished using electrophoresis. When an electric current is applied to the gel, DNA will migrate toward the positively charged electrode because it is negatively charged. Because shorter DNA strands move through the gel more quickly than longer ones, the DNA fragments are arranged in size order. Due to their negative charges, DNA and RNA are drawn toward the positively charged end of the gel.

Therefore, if DNA were placed at the top of the gel but the positive and negative poles were accidentally switched, we can say that all DNA molecules would move to the top of the gel.
