MacConkey Agar contains crystal violet which binds to gram positive bacteria, preventing them from growing. The media turns yellow in response to the production of acid when lactose is fermented. Which two terms best describe this media

Answers

Answer 1

Answer:

The media describes Selective  and Differential.

Explanation:

Given - MacConkey Agar contains crystal violet which binds to gram positive bacteria, preventing them from growing. The media turns yellow in response to the production of acid when lactose is fermented.

To find - Which two terms best describe this media ?

Proof -

The media describes Selective  and Differential.

Reason -

MacConkey is a selective and differential media.

This media is used to selectively isolate gram-negative bacteria from other bacteria and differentiate them on the basis of lactose fermentation.

Lactose fermenters turn red or pink on MacConkey agar, and non-fermenters do not change color.

According to the Big Bang theory, what happens if you reverse the galaxy motion and go back in time?
A. Everything would become condensed into one dense point
B. Some things would remain the same, while others go back
C. Everything would be the same as it is today.
D. You would find everything in a large cloud of cold isolated gas

Answers

I believe the answer is A

According to the Big Bang theory, if you reverse the galaxy motion and go back in time A. Everything would become condensed into one dense point.

The Big Bang Theory simply explains how the universe was formed from a large explosion. According to the Big Bang theory, the universe was formed as a result of the explosion of particles.

The reverse of the Big Bang Theory simply means the scenario where the expansion of the universe reverses. This is also called the Big Crunch. This will lead to the recollapse of the universe.

In this case, the cosmic scale also reaches zero. Then, everything would become condensed into one dense point.

To get rid of waste generated by thousands of sailors aboard each of its aircraft carriers, the US Navy is using a process called pyrogenesis. In this process, waste is subjected to extraordinary heat. How is pyrogenesis different from the process of setting garbage on fire in a landfill

Answers

Answer:

Its location.

Explanation:

The main difference between pyrogenesis and setting garbage on fire in a landfill is that pyrogenesis process occurs on the surface whereas garbage on fire in a landfill occurs inside the soil at certain depth. Pyrogenesis is an extreme thermal process that converts organic matter into gas made up of hydrogen and oxygen whereas garbage on fire in a landfill decomposes garbage that breaks down materials in simpler substances.

Imagine researchers following up on seeley's study brought some flat periwinkles appledore island into the lab to test for heritability. What results could they observe that would support the hypothesis that shell thickness is heritable in these snails?

Answers

Answer:

If thick-shelled snails have thick-shelled offspring and thin-shelled snails have thin-shelled offspring then this is good evidence that shell thickness is heritable.

Explanation:

Inheritance is a natural mechanism by which genetic information contained in the DNA sequence is passed from parents to offspring. Moreover, heritability is a measure of the genetic influence on the variation in a particular phenotypic trait (e.g., height, eye color, etc.) between individuals in a population. The values of heritability for a particular phenotypic trait range from zero (when all variation in a population comes from environmental factors and therefore is not heritable) to one (when all variation in a population comes from genetic factors and therefore is heritable). For example, in this case, if parental snails always have offspring with the same phenotype for the trait ‘shell thickness’, it would indicate that the heritability for this trait is equal to one, thereby evidencing that all of the variability for the trait 'shell thickness' comes from genetic differences.

Comprehensive detail and links between structure and functions of cells and different tissue in animals

Answers

The main diffrence between their tissue is

1.Plant structure is different from the animal skeletal structure. A plant tissue is different from those in animals. Plant tissues are basically divided into two: Meristematic tissue and Permanent tissue.

Meristematic tissue: These tissues comprise of cells which have the dividing capacity. They are immature and help plants to divide continuously throughout the life. Depending on the site of location, it is of three types. Apical, lateral and intercalary meristems. These meristems enlarge the cell and increase the length and width of the stem, roots and leaves.

Permanent tissue: Permanent tissues are derivative of meristematic tissue. They don’t have the dividing capability but aid in other functions like conduction of substances, storage of food etc. Two types of permanent tissues are found in plants i.e. simple and complex permanent tissue. Simple permanent tissues include parenchyma, collenchyma and sclerenchyma while complex tissues are xylem and phloem.

Animal body is made of four different types of tissues.

Epithelial Tissue

Muscle Tissue

Connective Tissue

Nerve Tissue

Epithelial Tissue: All organs in the body are lined with a group of tissues called epithelial tissues. They cover the surface of all internal as well as external organs. There are four types of epithelial tissues: Squamous epithelium, Stratified epithelium, Cuboidal epithelium and Columnar epithelium. They may be cuboidal, columnar or even flat. The main functions of these tissues involve protection, secretion, absorption, sensation etc..

Muscle Tissue: This type of tissue forms three types of muscles, namely skeletal (striated or voluntary) muscle, smooth (unstriated or involuntary) muscle and cardiac (heart) muscle. They help in movement by contraction and relaxation of muscles.

Connective Tissue: As the name suggests, they connect the different tissues, organs and parts of the body. Different types of connective tissues are Areolar tissue, Adipose tissue (fat), Blood, Lymph, Bone and Cartilage. They connect and support organs and also transport substances between organs.

Nervous Tissue: These tissues are made up of specialised cells called nerve cells (neurons). They conduct and transmit electrochemical impulses between neurons.

High Altitude Living Quick Check

Tibetans' physiological adaptations make them less likely to suffer from pulmonary hypertension (or high blood pressure). So, the correct option is C.

What do you mean by Adaptations?

Adaptations may be defined as the evolutionary process where an organism becomes better suited to its habitat, in order to survive and reproduce in it.

Tibetans are adapted to high altitudes by producing fewer red blood cells. They have greater hypoxic and hypercapnic ventilatory responsiveness. They have large lungs, and greater lung diffusing capacity. This leads them less likely to suffer from pulmonary hypertension.

Therefore, Tibetans' physiological adaptations make them less likely to suffer from pulmonary hypertension (or high blood pressure).

Two dogs–a boxer and a poodle–were the first to have their entire genomes sequenced. The dog genome contains 2.8 billion2.8 billion base pairs across 3939 pairs of chromosomes. They have 19,00019,000 protein-coding genes, most of them with close counterparts in other mammals, including humans. What is the total number of chromosomes in a dog?

Answers

Answer:

78 chromosomes

Explanation:

Since the number of chromosomes in a dog are diploid, we have 2n chromosomes where n = number of chromosome pairs.

Since n = 39.

The number of chromosomes is 2n = 2 × 39 = 78 chromosomes

So, a dog has 78 chromosomes.

Nonvascular plants have never evolved to the size of vascular plants, most likely because they lack Select one: a. a photosynthetic mechanism. b. an efficient mode of respiration. c. an efficient system for conducting water and minerals. d. nutrient and water absorption mechanisms. e. They lack all of these choices.

Answers

Answer:

The correct answer is c. an efficient system for conducting water and minerals.

Explanation:

Non-vascular plants lack the internal tubes or vessels that carry water and minerals or nutrients through the entire plant. Most of them are found in humid or submerged places, since this type of environment allows them to absorb water through the surface of their tissues. Non-vascular plants do not grow very tall due to the lack of structures normally associated with vascular plants. Non-vascular plants lack specialized vascular tissue (xylem and phloem) for conduction and internal support of water and food. Metabolites and other nutrients are transferred between and within cells by osmosis, diffusion, and cytoplasmic flow.
