[tex]\\ \sf\longmapsto Avg\: Velocity=\dfrac{Total\: displacement}{Total\:time}[/tex]
[tex]\\ \sf\longmapsto Avg\: Velocity=\dfrac{6800}{7200}[/tex]
[tex]\\ \sf\longmapsto Avg\: Velocity=0.9420m/s[/tex]
Answer:
0.9420m/s north
Explanation:
Given,
Displacement (Total) = 6800 metres(m)
Time = 2 hours
We need to convert hours to seconds.
2 hours = 7200 seconds
We know,
[tex]\sf\longmapsto \: Average \: velocity = \frac{Total \: Displacement}{Total \: time} [/tex]
Let's start solving!
[tex]\sf\longmapsto \: Average \: velocity = \frac{6800 \: metres}{7200 \: seconds} [/tex]
[tex]\sf\longmapsto \: average \: velocity = 0.9420\: m/s[/tex]
Which structural data is normally used to classify mosses into the category Bryophyta?(1 point)
They are large.
They lack roots.
They produce flowers.
They produce seeds.
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.
What are the characteristics of Bryophyta?The characteristics of the Bryophyta are as follows:
The plant body is mostly thallus-like, i.e. erect or prostate.They are generally attached or linked to the substratum by rhizoids. They significantly lack true vegetative structure. The plants are generally green and have chloroplast.They express an autotrophic mode of nutrition.Vascular tissues like the xylem and phloem are completely absent.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.

What is the difference between a vertebrate and invertebrate?
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. They either have a soft body, like worms and jellyfish, or a hard outer casing covering their body, like spiders and crabs.

HELP PLEASE!!!explain how Earth is heated through conduction
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.

What is incomplete dominance?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).

Protein Folding Notes
Answer:
"Protein folding occurs in a cellular compartment called the endoplasmic reticulum. This is a vital cellular process because proteins must be correctly folded into specific, three-dimensional shapes in order to function correctly. Unfolded or misfolded proteins contribute to the pathology of many diseases."
Explanation:
how the function of the basal cells depends on the relationship among its parts?(respiratory system )
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.

how plating trees can be a problem
Answer:
(Hope this helps can I pls have brainlist (crown)☺️)
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.

d. Chromosomes line up single file, separate, forming diploid cells
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.
