Answer:

What is c. Chromosomes line up single file, separate, forming haploid cells

In meiosis I, chromosomes in a diploid cell resegregate, producing four haploid daughter cells. It is this step in meiosis that generates genetic diversity. DNA replication precedes the start of meiosis I. During prophase I, homologous chromosomes pair and form synapses, a step unique to meiosis.

As it's known conduction needs a medium for heat transfer and during the day, sunlight rays pass through the Earth's atmosphere and near the earth's surface is where most heat transfer by conduction occurs since air is a poor conductor. Thus, the sunlight hits the earth's surface(ground) and in turn heats the air above it and transfering the heat.

It must be known that conduction happens mostly near the earth's surface.

Answer:

Conduction is one of the ways that energy is transferred from the earth's atmosphere to the air. Conduction is the process by which heat energy is transmitted through collisions between neighboring molecules. Think of a frying pan set over an open camp stove.

A white rooster (WW) is crossed with a black-and-white-speckled hen (Ww).

The hen lays eight eggs.

Incomplete dominance is a form of Gene interchange in which both alleles of a gene at a locus are somewhat expressed, often resulting in a medium or separate phenotype.

It is also known as partisan dominance.

For Example in roses, the allele for red colour is dominant over the allele for white colour.

Thus, A white rooster (WW) is crossed with a black-and-white-speckled hen (Ww).

Explanation:

There are even more serious issues, as trees have several ways of influencing the climate. The first problem is that trees are dark in comparison to other things that could cover the ground, such as grass or snow. Planting more trees, as a result, tends to make the terrain darker.

Tree planting on a large scale is becoming a more popular part of worldwide efforts to fulfil climate objectives. Forests, on the other hand, are complex ecosystems, and haphazard planting can actually raise carbon dioxide (CO2) levels in the atmosphere, contributing to global warming.

The dichotomous key is a classification tool based on morphological characteristics. The correct option is B. Dichotomous keys can only be used to classify organisms based on their observable traits.

A dichotomous key might be considered a significantly useful tool to classify organisms.

The key provides an easy and fast way for identification by describing different morphological observable traits, leading you to the correct taxonomic classification.

The term dichotomous refers to how information is provided. You will always have two options (a and b, or 1 and 2), and you will have to choose one of them according to the characteristics of your organism.

Each time you choose an option, it leads you to the following description, which gets more specific each time.

Probably you might need an atlas or a dictionary to understand some of the technical terminologies.

You will also need to carefully observe your specimen, to get to distinguish different traits. If the specimen is too small you might need a loup.

The correct statement is B. Dichotomous keys can only be used to classify organisms based on their observable traits.

Answer:

They lack roots

Explanation:

The structural data which is normally used to classify mosses into the category Bryophyta is that they lack roots. Thus, the correct option for this question is B.

The characteristics of the Bryophyta are as follows:

It is known that Bryophytes include embryophytes like hornworts, liverworts, and mosses. These are very small plants that remarkably grow in shady or damp areas where there is an enormous amount of mud is present.

Bryophytes have no roots, leaves, or stems. This characteristic is the root foundation or evidence that is used to classify mosses into the category of Bryophyta.

Therefore, the correct option for this question is B.

a vertebrate is an organism with a spinal cord, an invertebrate has no spinal cord

Answer:Vertebrates are animals that have a backbone inside their body. The major groups include fish, amphibians, reptiles, birds and mammals. Invertebrates don't have a backbone.

Answer:

Basal cells are found at the bottom of the epidermis — the outermost layer of skin. Basal cells produce new skin cells. As new skin cells are produced, they push older cells toward the skin's surface, where the old cells die and are sloughed off.

Answer:

The respiratory system works directly with the circulatory system to provide oxygen to the body. The primary function of the respiratory system is to deliver oxygen to the cells of the body's tissues and remove carbon dioxide, a cell waste product.Respiratory systems work together to circulate blood and oxygen throughout the body.The respiratory system subdivides into a conducting portion and a respiratory portion. The majority of the respiratory tree, from the nasal cavity to the bronchi, is lined by pseudostratified columnar ciliated epithelium. The bronchioles are lined by simple columnar to the cuboidal epithelium, and the alveoli possess a lining of thin squamous epithelium that allows for gas exchange.The conducting piece of the respiratory system consists of the nasal cavity, trachea, bronchi, and bronchioles. The luminal surfaces of this entire portion have a lining of ciliated pseudostratified columnar epithelium and contain goblet cells. Their role is to secrete mucus that serves as the first line of defense against incoming environmental pathogens. Cilia move the mucus-bound particulate up and away for expulsion from the body. The various types and abundance of cells are dependent on which region of the airway they are.
