When do land breezes develop? Which way does wind move during a land breeze?
Answer:
A low-pressure zone forms above the land surface from the rapid loss of heat. A high-pressure zone forms as the cooler land cools the air immediately above the surface. Winds aloft flow from the ocean to the land. Winds at the surface flow from high to low pressure, creating a land breeze

a. positive
b. negative
Answer:
The correct answer is - option a. positive.
Explanation:
Nittarte reduction is the test for the determinantion of the production of nitrate reductase enzyme through various test. One of the test is trommsdroff test.
This test involves trommsdroff reagent and dilute sulfuric acid that produce blue color if the reduction occurs and reductase present. This color is formed due to the conversion of ammonia to nitrate.

Considering the drifting of continents, how do you explain the abundance of marsupials and the absence of native placental mammals in Australia
Answer:
this phenomenon is a natural consequence of evolutionary processes and continental drift
Explanation:
Marsupials are mammals in which newborn offspring are carried in a pouch of the female (mother) body. On the other hand, placentals are mammals that complete embryo development in the mother's body, in the placenta. All the extant marsupials are endemic to Australia and the Americas. It has been shown that marsupials diverged (evolved) in South America, Australia and Antarctica when these landmasses were joined. In Australia, marsupials evolved to fit an ecological niche, which can be attributed to geographic isolation due to continental drift, while placental mammals are relatively recent and more scarce (mainly bats and rodents) within this region.

Xylem
O
Aerenchyma
O
Sclerenchyma
Answer:
The correct answer is - Sclerenchyma
Explanation:
Sclerenchyma are the dead cells with narrow lumen lignified cells. These dead cells has numerous pits that helps in trading the various substances to neighboring cells. At matuarity, hese cell lack the protoplast so therefore called dead cells .
Sclerenchyma cells are lignified which makes them thick and these cells help in the supporting the plants. These cells are impereable to almost everything gases, substances and many more.
Calculate the amount of energy you would expect to find at the secondary consumer level if there were 100,000 J of energy at the producer level in an ecosystem.
The amount of energy one would expect to find at the secondary consumer level if there were 100,000 J of energy at the producer level in an ecosystem is 1000J.
How to calculate amount of energy available in food chain?The food chain is a feeding relationship between living organisms in an ecosystem. Each organism occupies a position called trophic level.
The trophic levels involved in a food chain are as follows:
ProducerPrimary consumersSecondary consumersTertiary consumerThe producer begins the energy transfer, however, only 10% of the available energy is passed to the next trophic level because 90% of this energy is used for metabolic activities.
This means that if 100,000 J of energy is available at the producer level in an ecosystem, the following applies:
Primary consumers: 10/100 × 100,000 = 10000J of energy Secondary consumers: 10/100 × 10,000 = 1000J of energyTherefore, the amount of energy one would expect to find at the secondary consumer level if there were 100,000 J of energy at the producer level in an ecosystem is 1000J.

During G2 the Wee1 protein phosphorylates tyrosine-15 of the Cdc2 protein kinase, thus inactivating it. Only once dephosphorylation occurs and Cdc2 becomes active carn the cell pass from G2 into M and proceed to cell division. Can you think of a reason why the Wee1 protein was named as such?
Answer:
cells can't fully grow in Wee1 mutants
Explanation:
The G2 phase is a period where cell growth and proteins are synthesized to prepare for cell division. The Wee1 protein is a dosage-dependent inhibitor of mitosis. Moreover, the cyclin-dependent kinase 2 (cdc2) is a protein involved in the regulation of the cell cycle which phosphorylates serine residues in Wee1. However, in Wee1 mutants, Cdc2 is not inactivated (phosphorylated). This change causes cells to enter M phase prematurely, thereby producing "wee" mutant cells.
