A 2,500-kg car hits a fence with a force of 400 N, and the collision takes one

Biology
1 answer:
NISA [10]4 years ago
3 0

Answer:B. 400 kg-m/s

Explanation: To calculate impulse(I)

I = Force×time

where;

Force=400N

Time=1 seconds

I=400N×1 sec

I=400kg-m/s

Where,force =kgm/s^2

And time =seconds

Therefore the impulse unit =kgm/s

After infection of a cell, a viral particle must transport itself to the nucleus in order to produce viral proteins. What is the
kykrilka [37]

Answer:

Double-stranded DNA

Explanation:

If a virus requires to transport its genome in the nucleus to produce viral protein then the viral genome content must be DNA. This DNA of the virus will use the RNA polymerase of the host cell and will first convert into mRNA in the nucleus.

Then the mRNA of the virus will come out of the nucleus because the protein synthesis takes place outside the nucleus and in the cytoplasm. So in the cytoplasm by using host translational machinery the viral mRNA will code for viral proteins. So the correct answer is double-stranded DNA.

In cells where telomerase is normally inactive, it can become active by accident and often, cancer will develop as a result. Can
vesna_86 [32]

Answer:

Cancer cells achieve proliferative immortality by activating or upregulating the normally silent human TERT gene (hTERT) that encodes telomerase, a protein with reverse transcriptase activity that complexes with other proteins and a functional RNA (encoded by hTR, also called hTERC) to make a ribonucleoprotein enzyme.

Explanation:

A rare cell that escapes crisis almost universally does so by reactivating telomerase and this cell can now become a cancer cell with limitless potential to divide. Almost all cancer cells have short telomeres and thus inhibitors of telomerase should drive such cancer cells into apoptotic cell death. Yet, each time a cell divides, the telomeres get shorter. When they get too short, the cell no longer can divide and becomes inactive or "senescent" or dies. This process is associated with aging, cancer, and a higher risk of death.

How are the Kissimmee River, Lake Okeechobee, and the Everglades related?
Taya2010 [7]
Between 1962 and 1971, the United States Army Corps of Engineers (USACE) channeled the Kissimmee River and created a 30-foot deep, 300-foot wide, 56 mile long drainage canal (C-38). This project converted 44% of the floodplain to pasture, draining approximately 31,000 acres of wetlands. Before channelization, the River was a haven for wildlife, including at least 39 species of fish and 38 species of water birds.

Kissimmee River Restoration began in 1992 and has been the most successful ecosystem restoration initiative to date. By re-channelizing the River to replicate its natural paths, birds and other wildlife responded more quickly than anticipated and demonstrated the resiliency of nature. This success has been used all over the world to justify the value of ecosystem restoration. When Kissimmee River Restoration is completed in 2015, more than 40 square miles of the River-floodplain ecosystem will be restored, including almost 20,000 acres of wetlands and 44 miles of historic river channel.
