What are the bones present in the chest?
The bones of the thorax are the thoracic vertebrae, the twelve pairs of ribs, and the sternum. Connecting the upper ten pairs of ribs to the sternum are the costal cartilages.
The first rib is quite small. Like all the ribs, it's angled downward from back to front.
The thorax is commonly known as the chest. The thorax expands in a dome-shaped pattern to roughly two thirds of its full width from the first to the third rib. The thorax spreads a bit more, forming a cone-shaped structure, from the third rib to the seventh. The thorax somewhat narrows and the ribs significantly shorten between the seventh and the twelfth ribs.
The manubrium, the body, and the xiphoid process, or xiphisternum, make up the sternum, also referred to as the breast bone.
The manubrium is joined to the sternum's body via a cartilaginous joint that allows for some movement. The top border of the manubrium and the sternal angle, a minor angle between the manubrium and the body, are both easily palpable.

what would happen to the leaf if the stomata were open all the time?
The process of transpiration, which occurs when water evaporates from the surface of leaves, would be excessive if stomata were always open.
They can expand or contract to open or close the pore, which is essential for controlling gas exchange for photosynthesis as well as moisture levels in tissues. According to Torii, who is also a professor at Nagoya University in Japan, if plants cannot produce stomata, they are not alive and cannot "breathe."
Increased water loss is a drawback of wide open stomata (transpiration). Cool-season turfgrass stomata must make choices as a result. Yet, if a plant loses too much water through transpiration, it may become injured or die. Photosynthesis is how a plant gathers and stores energy.

how was it determined that dna carries genetic information
The determination that DNA contains genetic information was made by a series of scientific experiments over the course of many years.
Oswald Avery and his team produced one of the earliest significant discoveries in 1944.
They found that the substance responsible for changing bacterial genetic traits was DNA. This was discovered by combining a certain strain of bacteria that could break down a specific sugar with a strain of bacteria that was unable to do so.
Further investigation led to the discovery that DNA contains the genetic information necessary for the production of proteins in living things.
The double-helix model of DNA, which was created in 1953 by James Watson and Francis Crick, described how the structure of DNA contained genetic information in the form of four bases.
This finding paved the way for more investigation, which in turn made it possible to sequence and study DNA in order to compare the genetic make-up of other creatures.

the turnover number for this enzyme and substrate is 1.00×104 per minute. how long would it take one molecule of urease to produce 987 product molecules?
It would take one molecule of urease approximately 0.094 minutes (or 5.64 seconds) to produce 987 product molecules.
The turnover number for an enzyme is defined as the maximum number of substrate molecules that an enzyme can convert into a product per unit of time when the enzyme is saturated with substrate. In this case, the turnover number for the enzyme and substrate is 1.00 × 104 per minute, which means that one enzyme molecule can convert 1.00 × 104 substrate molecules to the product in one minute.
To determine how long it would take one molecule of urease to produce 987 product molecules, we need to use the turnover number and some basic math. Since one molecule of enzyme can convert 1.00 × 104 substrate molecules to the product in one minute, we can calculate how many minutes it would take for one molecule of the enzyme to produce 987 product molecules as follows:
1 minute / 1.00×104 product molecules = x minutes / 987 product molecules
Solving for x, we get:
x = 987 / 1.00×104 = 0.094 minutes
