Answer:

Carpel is the female part of the flower.

Explanation:

The carpel is the female part of the flower and also known as gynaeceum. It has 3 parts - ovary, style, and stigma. The ovary is the base of the carpals. It consists of locules or chambers within which ovules are present. The ovary may be a single chamber or multi chambers or locules. The double-chambered ovary is called bilocular and more than 2 chambers are known as polylocular. The second part is the style of the carpals. The style connects the ovary with stigma. The 3rd and apex part of the carpel is a stigma. It receives pollen during pollination.

Cells can function____ A. in rapidly changing temperatures and pHs. B. in a wide range of pHs and temperatures. C. only in a nar

irakobra [83]

Correct answer: C) Only in a narrow range of temperature and pH

Homeostasis is defined as the ability of the body to regulate temperature and internal conditions even when there is a change in the external environment. Homeostasis is important for the survival of life because the cells of all the organism can function well only in a limited range of temperature and pH.

All the cells of the body use enzymes for proper function, and the enzymes can only function under a limited range of temperature and pH. In extreme conditions of cold or heat enzymes will not be able to function properly and lead to the death of the cell.

What is the energy requirement in kJ/mol to transport a proton across the mitochondrial inner membrane in plant cells at night w

lions [1.4K]

Answer:

C. +23.1 kJ/mol

Explanation:

the formula to use to calculate the energy requirement in kJ/mol to transport a proton across the mitochondrial inner membrane in plant cells is:

ΔGt = RTIn $\frac{C_{2} }{C_1}$ + ZFΔV

let's list the values of the data we are being given in the question to make it easier when solving it.

Z= 1

F= 96500C (faraday's constant)

ΔV= 160mV = 0.160V

R= 8.314( constant)

T= 15ºC ( converting our degree Celsius into kelvin, we will have 273.15k+ 15 = 288.15K)

∴ T= 288.15K

Putting it all together in the formula, we have:

ΔGt = 8.314 × 288.15 × 2.303 log $\frac{C_{2} }{C_1}$ + 1 × 96500 × 0.160

ΔGt = 5517.25 $[ -(log(H^{+}_{out} ) + log(H^{+}_{in} )_{in}$ +15440

ΔGt = 5517.25 $(pH_{out} - pH_{in}$ +15440

Given that the pH differential gradient across the membrane is 1.4pH units. It implies that;

ΔGt = 5517.25 × 1.4 + 15440

= 7724.15 +15440

= 23164.15 Joules/moles

= +23.1 KJ/mole

An individual is heterozygous for a gene at a specific locus. ________ will have the same form of alleles at that locus after S

neonofarm [45]

Answer:

Explanation:

Sister chromatids will have the same form of alleles at the locus after S phase.

This is because during the S phae of the cell cycle, sister chromatids are replicated in preparation for cell division. The replication process is quite accurate such that all the alleles present on the initial chromatids are also replicated on the new sister chromatids. Hence, both new and old chromatids will have the same form of alleles at the locus after replication at the S phase. In other words, sister chromatids are exact copy of one another.

The correct option is D.
