What kind of mixture is blood
Answer:
Blood is a colloid which mainly contains red and white blood-cells, lymphocytes and plasma.
Explanation:
Believe it or not but blood is considered an organ. That’s because it contains a collection of different types of cells suspended in a liquid, the plasma.
The most obvious type of cell is the red blood cell (erythrocytes), which provides the red color to the blood and more importantly contains haemoglobin, an iron holding protein that binds oxygen or carbon dioxide. This way these gases are transported throughout the body. Oxygen towards the tissues, carbon dioxide outward of course.
Another very important blood cell type are the white ones (leukocytes). Without going into much detail (a lot of different subtypes exist) the white blood cells are responsible for one’s immunity. Some of these cells called macrophages like to swallow stuff that’s not supposed to be in your blood.
A third important type of cell, the smallest ones, are the trombocytes or platelets. The make sure you blood coagulates when you are wounded. Without them you would bleed to death.
Besides these cells a lot of different molecules or ions are dissolved or suspended in the plasma : proteins of which a lot of albumin, vitamins, minerals. The steady bloodstream makes sure every cell in your body is provided with the nutrients it needs.
If you visited a savanna you would most likely see
If you visited a savanna, you would most likely see vast grasslands with scattered trees or shrubs.
Savannas are tropical or subtropical ecosystems characterized by a mix of grasses and scattered vegetation. They are often found in regions with a pronounced dry and wet season. One of the distinctive features of savannas is the presence of herbivores such as zebras, wildebeest, giraffes, and antelopes, which graze on the grasses.
These herbivores, in turn, attract predators like lions, cheetahs, hyenas, and leopards, which can often be observed hunting and feeding on the herbivores. Other common wildlife in savannas includes elephants, buffalo, and various bird species. The open landscape and diverse animal life make savannas popular destinations for wildlife safaris and nature enthusiasts.

when a cell undergoes mitosis,what is the result?
When a cell undergoes mitosis, it forms two daughter cells which have the same number of chromosomes as the parent cell.
What is mitosis?Mitosis is a process used to create more cells that share the same genetic makeup as the parent cell. It is crucial for the growth and development of human bodies as well as for the embryonic development of living things. Mitosis generates new cells and replaces injured, destroyed, or aging ones.
Somatic cells undergo mitosis, which means that all cell types whose function is not the generation of gametes go through this process. Each chromosome is duplicated before each mitotic division, resulting in a full set of chromosomes in the nucleus of each new cell after division.
Thus, when a cell undergoes mitosis, it forms two daughter cells which have the same number of chromosomes as the parent cell.

This type of water has a very low salt content when compared to the ocean.
Answer:
Freshwater
Explanation:
Freshwater is usually defined as those water bodies that are comprised of relatively very less amount of salt content. This includes rivers, lakes, and ponds. The amount of salt present in these water bodies is less than 1%, thereby providing the water on which the living beings are dependent on. It is comprised of less than 500 ppm of dissolved salts. These water bodies support a large number of aquatic animals.
Whereas, the ocean water body is comprised of high salinity.
Thus, the freshwater bodies contain low very salinity compared to the ocean water body.
Which type of electromagnetic radiation is the only type that humans can see with their eyes? (2 points) Gamma rays Ultraviolet rays Visible waves Rays
Humans can only see visible light, with a wavelength range of 380 to 740 nm, which falls within the larger electromagnetic spectrum.
The type of electromagnetic radiation that humans can see with their eyes is called visible light. This form of radiation has wavelengths that range between approximately 380 and 740 nanometers (nm). The electromagnetic spectrum is vast and includes other types of radiation like gamma rays, ultraviolet rays, infrared light, microwaves, and radio waves, none of which can be seen by the human eye. Visible light represents a very small portion of the electromagnetic spectrum but is essential for human vision, as our eyes are sensitive to this range of wavelengths.
Gamma rays have the shortest wavelengths and are highly energetic and potentially harmful, but they are absorbed by Earth's atmosphere. Ultraviolet (UV) rays have slightly longer wavelengths than visible light but are still too short for us to see. Infrared light has longer wavelengths and can be felt as heat rather than seen. Radio waves have the longest wavelengths and the least energy and are also not visible to humans. The capacity to see visible light is an evolutionary adaptation to the types of waves that effectively reach Earth from the sun and penetrate our atmosphere without being blocked except by clouds.

one reason that electric power plants do not send out electrical energy as a direct current is that direct current can not be transformed explain why
This is because direct power has no pulsation (waveform characteristic) that is significant in electromagnetic induction. The gradual increase and decrease of power, at a given frequency, in indirect power is significant in electromagnetic induction. This enables transformers to induce electricity into the secondary coil, from the primary coil, at the core of the transformer.Transformers transform electric power by increasing or decreasing the voltage and current of electricity.

One difference between organisms being classified as Kingdom Plantae or Kingdom Animalia is the way the organism gets food. Which statement correctly states the difference between the two kingdoms?
A) Kingdom Plantae organisms are herbivores and Kingdom Animalia organisms are carnivores.
B) Kingdom Animalia organisms are herbivores and Kingdom Plantae organisms are carnivores.
C) Kingdom Plantae organisms make their own food and Kingdom Animalia organisms do not make their own food.
D) Kingdom Animalia organisms make their own food and Kingdom Plantae organisms do not make their own food.
The right option is; C)
Kingdom Plantae organisms make their own food and Kingdom Animalia organisms do not make their own food is the statement that correctly states the difference between the two kingdoms.
All organisms in Kingdom Plantae are autotrophs. They have the ability to make their own food from inorganic substances through the process of photosynthesis, while all organisms in the Kingdom Animalia are heterotrophs. They do not have the ability to make their own food but they depend on other organisms for their food.

An mRNA strand has 204 bases to code for a protein from start to stop. how many amino acids will the resulting protein contain
The mRNA strand with 204 bases will code for a protein containing 67 amino acids, as each amino acid is defined by a three-nucleotide sequence, the codon. The subtraction of one is due to the stop codon which does not code for an amino acid.
Explanation:A protein sequence is made up of a chain of amino acids, each of which is coded by a three-nucleotide sequence in mRNA, known as a codon. Based on the number of bases in the mRNA strand, we can determine how many amino acids it will produce by dividing the total number of bases by three. In this case, the mRNA stand has 204 bases. However, the start and stop codons are also included in this count. So with 204 bases and 3 bases per codon, we have 68 codons. However, since one of these is a stop codon which does not code for an amino acid, the resulting protein will contain 67 amino acids.

The plant Arabidopsis Thaliana Has a gene which has been found to show an unusually high rate of mutation which conclusion is best supported by this observation?
A. The genus control by environment and not heredity
B. Traits associated with this gene may vary greatly in the species
C. Traits associated with this gene are beneficial to the species
D. The gene codes for flower color in the plant
Answer;
The correct answer would be option B.
Mutation refers to the random change in the nucleotide sequence of the DNA.
If a mutation occurs in a protein coding sequence of the DNA, it can result in the change of phenotype of a gene.
Thus, if a gene has a high mutation rate in a population, then the genetic variation for that gene must be high in a population.
The high genetic variation would result in high variation in the phenotype or trait associated with that gene.
