I’m very much confused

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.

Answer:

So, heating a magnet disrupts the domain walls and it becomes easy for the magnetic domains, which are ordinarily lined up, to rotate and become misaligned. They are now less aligned and point in the opposite direction to their neighbors, causing a decrease in the magnetic field and loss of magnetism.

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.

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).

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.

Explanation:

Up to the the population carrying capacity the the population will increase to give a perfect balance and when the population will be much then the population will decrease.

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.

Answer:

During meiosis , four daugther cells are produced

Answer:

4 cells. You end up with four cells.

Explanation:

Each daughter cell undergoes meiosis-II, producing two cells. In meiosis-II the separation of two chromatids occur so that equal number of chromatids (in fact chromosome due to duplication of genetic material) goes to each of the daughter cell.

Thus, at the end of meiosis-II, four daughter cells are formed. Each cell has half the number of chromosomes present in the diploid cell.

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.

The statement that best describes a difference between the nitrogen and carbon cycles is the nitrogen cycle requires a process called nitrogen fixation that is carried out by certain bacteria.

The main difference between nitrogen cycle and carbon cycle is that nitrogen cycle describes the conversion of nitrogen into multiple chemical forms and its movement between the different ecosystems. Whereas the carbon cycle describes the movement of carbon and its multiple chemical forms between the atmosphere, lithosphere and hydrosphere.

Microbes are involved in the nitrogen cycle process. Both plants and animals participate in the carbon cycle.

Thus, the statement that best describes a difference between the nitrogen and carbon cycles is option (b).

Explanation:

Bacteria reproduce most quickly .  Fruit flies can go from the egg to sexual maturity in 3 weeks while bacteria can reproduce once they are "born" and can do so multiple times a day, while fruit flies can reproduce if mature once every day about.  

Finches and humans obviously have much slower rates of reproduction.
