= 3600 N
I hope this helps
An automobile with a mass of 1200 Kg accelerates at a rate of 3 m / s2 in the forward direction. The net force acting on the automobile is 3600 N.
What is force?The push or pull on a mass-containing item changes its velocity. An external force is an agent that has the power to alter the resting or moving condition of a body. It has a direction and a magnitude. Force is calculated by multiplying the mass by acceleration.
The product of the molar mass of the compound and the moles of the substance are defined as mass
Here, the automobile has some mass and acceleration. And the force that is acting on the automobile is to be calculated.
Given, the mass is 1200 Kg
The time is 3 m/s2
Force = Mass × Acceleration
1200 × 3 = 3600 N
Therefore, the net force acting on the automobile is 3600 N.

If albumen is broken down by a protease, what sort of chemical is albumen?
Albumin is broken down by the activity of protease enzyme, this enzyme is responsible for the digestion of proteins. Therefore, albumin is chemically protein in nature.
What is Albumin?
Albumin is a family of proteins. These are globular proteins in which the most common are the serum albumins. All the proteins of the albumin family are water-soluble and moderately soluble in concentrated salt solutions. This protein denatures on continuous heat treatment.
Albumins are commonly found in blood plasma. It differs from other blood proteins as they cannot be glycosylated. Substances which contains albumin proteins are called albuminoids.
A number of blood transport proteins are found to be evolutionarily related in the albumin family such as serum albumin, alpha-fetoprotein, vitamin D-binding protein and afamin. This family of proteins is only found in vertebrates.

How does thermohaline circulation force the thermocline toward the
ocean's surface?
Thermohaline circulation begins in the Earth's polar regions. When ocean water in these areas gets very cold, sea ice forms.
What is Thermohaline circulation?The thermohaline circulation (THC) is that part of the ocean circulation which is driven by fluxes of heat and freshwater across the sea surface and subsequent interior mixing of heat and salt.
What is polar region?The areas of the Earth that encircle its geographical poles and are contained inside the polar circles are known as the polar regions, sometimes known as the frigid zones as well as polar regions.
These deep-ocean currents are driven by differences in the water's density, which is controlled by temperature (thermo) and salinity. This process is known as thermohaline circulation. In the Earth's polar regions ocean water gets very cold, forming sea ice.Thermohaline circulation begins in the Earth's polar regions. When ocean water in these areas gets very cold, sea ice forms. The surrounding seawater gets saltier, increases in density and sinks. Winds drive ocean currents in the upper 100 meters of the ocean's surface.

Is the Harvard Forest a carbon source or a carbon sink, and how has the net ecosystem exchange (NEE) changed over time?
Answer:
This is strong evidence that suggests that the forest acts as a carbon “sink”: each year, it removes more CO2 from the air than it produces.
Explanation:
There are different sources of carbon. Harvard Forest is known to be a carbon sink.
Harvard Forest is known to have active C sink that is due to the forest regrowth after land abandonment.
Net ecosystem exchange is known to be negative every year. but the result is shown to be very variable. Result also show a decrease over time and this implies that the forest is removing more CO2 from the atmosphere presently than before.
When you look at the data of the last 25 years, there is a pattern of NEE being negative and also many variability.

Sketch and label a general life cycle diagram of a
gymnosperm. Your diagram must include the following: female cone, male cone, pollen grains, scale, seeds, eggs, adult sporophyte, pollination, germination, fertilization.
Answer:
?
Explanation:
Characteristics of Gymnosperms
Gymnosperms are seed plants adapted to life on land; thus, they are autotrophic, photosynthetic organisms that tend to conserve water. They have a vascular system (used for the transportation of water and nutrients) that includes roots, xylem, and phloem. The name gymnosperm means “naked seed,” which is the major distinguishing factor between gymnosperms and angiosperms, the two distinct subgroups of seed plants. This term comes from the fact that the ovules and seeds of gymnosperms develop on the scales of cones rather than in enclosed chambers called ovaries.
Gymnosperms are older than angiosperms on the evolutionary scale. They are found far earlier in the fossil record than angiosperms. As will be discussed in subsequent sections, the various environmental adaptations gymnosperms have represent a step on the path to the most successful (diversity-wise) clade (monophyletic branch).
Gymnosperm Reproduction and Seeds
Gymnosperms are sporophytes (a plant with two copies of its genetic material, capable of producing spores ). Their sporangia (receptacle in which sexual spores are formed) are found on sporophylls, plated scale-like structures that together make up cones. The female gametophyte develops from the haploid (meaning one set of genetic material) spores that are contained within the sporangia. Like all seed plants, gymnosperms are heterosporous: both sexes of gametophytes develop from different types of spores produced by separate cones. One type of cone is the small pollen cone, which produces microspores that subsequently develop into pollen grains. The other type of cones, the larger “ovulate” cones, make megaspores that develop into female gametophytes called ovules. Incredibly, this whole sexual process can take three years: from the production of the two sexes of gametophytes, to bringing the gametophytes together in the process of pollination, and finally to forming mature seeds from fertilized ovules. After this process is completed, the individual sporophylls separate (the cone breaks apart) and float in the wind to a habitable place. This is concluded with germination and the formation of a seedling. Conifers have sperm that do not have flagella, but instead are conveyed to the egg via a pollen tube. It is important to note that the seeds of gymnosperms are not enclosed in their final state upon the cone.
Answer:
Gymnosperms produce both male and female cones, each making the gametes needed for fertilization; this makes them heterosporous.
Megaspores made in cones develop into the female gametophytes inside the ovules of gymnosperms, while pollen grains develop from cones that produce microspores.
Conifer sperm do not have flagella but rather move by way of a pollen tube once in contact with the ovule.

B. antibiotics are used to treat sick humans, and humans are living organisms.
C. antibiotics are viruses that have been deactivated but we're once alive.
D. antibiotics were first isolated from a living origin: mold.
Antibiotics are compounds capable of killing bacteria. This is biotechnology because antibiotics were first isolated from a living origin: mold. The correct option is D.
What are antibiotics?When the body develops a resistance to antibiotics, antibiotic resistance happens. Antibiotic abuse or overuse is what led to antibiotic resistance. When germs develop resistance to medications meant to kill them, it happens.
Because antibiotics are unable to combat bacteria, the bacteria grow and produce illnesses that can result in life-threatening infections, incapacity, or even death.
The overuse or improper use of antibiotics was somehow the cause of all antibiotic resistance. It takes place when the bacteria completely lose their ability to be killed by drugs and instead develop a resistance to them.
Therefore, the correct option is D. antibiotics were first isolated from a living origin: mold.
