Name the type of connective tissue that anchors the ribs onto the sternum.
Hyaline cartilage makes up the costal cartilage that holds the ribs to the sternum. The most prevalent form of cartilage in the body is hyaline cartilage.
What is hyaline cartilage?On the articulating surfaces of bones, in the larynx, trachea, and bronchi, as well as on the sternal ends of the ribs, hyaline cartilage is present. It imparts a rigid yet malleable form to the constructions.
Hyaline structures are connective tissues that anchor the ribs onto the sternum. Such structures and joints are robust because collagen fibers are present, but their mobility and flexibility are constrained. To reduce friction and provide cushioning at the joint surface, articular cartilage, also known as hyaline cartilage, covers the ends of bones.

A car travels 1300 km in 12 hours. What is its average speed?
The average speed by which the car travels according to the given scenario is 108.3 km/hr.
What is speed?The actual Speed is the calculated speed of the axis as determined by the change in the Transducer Counts status register. Actual Speed is measured in position units per second.
It can be calculated as total distance divided by the total time taken.
According to the given data:
The distance is 1300 km.
Time taken is 12 hrs.
[tex]Average speed = \frac{1300}{12} km/hrs[/tex]
Average speed = 108.33 km/hrs.

Which action has a positive effect on air resources?
using fossil fuels
building new homes
walking to work or school
removing vegetation such as trees
Answer:
Person above me or below me is correct :)
Explanation:
The answer is C !!
- Have a good summer :)
Utilising fossil fuels has a detrimental impact on air quality because they produce dangerous pollutants like carbon dioxide and nitrogen oxides when they are burned.
What are the contaminants linking to the air pollution ?These contaminants are linked to higher air pollution levels, which can lead to a variety of health problems, such as heart disease and respiratory disorders. The effects of new house construction on air resources are complex.
On the one hand, since burning fossil fuels for energy and releasing building materials can result in the emission of hazardous chemicals, construction may increase air pollution. On the other side, if new homes are constructed in places with fewer air pollution, as in rural regions, they may result in better air quality.
A benefit of walking to work or school an advantage for air resources. Walking does not emit any pollutants into the air, making it a zero-emission mode of transportation.
Additionally, walking lessens traffic on the roadways, which can lessen vehicle-related air pollution. Air resources may suffer if trees or other vegetation are removed. By providing shade, trees not only assist to filter airborne pollutants, but they also help to chill the air. Because air pollutants are not being filtered out as well when trees are cut down, this might result in higher air pollution levels.

A researcher proposes a model of an enzyme-catalyzed reaction in which a reactant is converted to a product.
What is enzyme catalysed reaction?Enzyme catalysis is the increase in the rate of a process by a biological molecule, an "enzyme". Most enzymes are proteins, and most such processes are chemical reactions. Within the enzyme, generally catalysis occurs at a localized site, called the active site.
The model is based on the idea that the reactant passes through a transition state within the enzyme-substrate complex before the reactant is converted to the product.

Which describes how mRNA is used by a cell? OA. It is used to check DNA for mutations. OB. It is used to move information to other cells. OC. It is used to replicate DNA for mitosis. OD. It is used to transfer genetic information.
Answer: D) it is used to transfer genetic info
Explanation: :)
The right response is OD. Genetic data is transferred through it. A specific kind of RNA molecule known as messenger RNA (mRNA) is in charge of transmitting genetic data from DNA to the ribosome, a cellular component in charge of creating proteins.
What is mRNA ?The single-stranded nucleotide molecule known as messenger RNA (mRNA) is translated from DNA. The ribosome then converts the sequence of amino acids, which serve as the building blocks for proteins, from the mRNA. When genes are expressed, which is the process of turning DNA-stored information into proteins, mRNA plays a crucial role.
The genetic information contained in DNA and the cell's machinery for protein synthesis are connected through mRNA. Involvement of mRNA in transcription mRNA plays a role in both the transcription of DNA into a series of nucleotides and the translation of that series of nucleotides into a series of amino acids.
The control of gene expression also involves mRNA. It may be applied to control both the time and volume of protein synthesis within a cell. By regulating the quantity of mRNA a gene produces, it may also be used to alter how active a gene is. This may be used to regulate the expression of particular proteins in a cell, which can have a significant impact on the cell's functionality.
