Answer:
False; The levels of carbon dioxide have significantly increased since the industrial revolution.
Answer:
they are both processes of cell division with the same steps.
Explanation:
you can also remember it as PMAT prophase metaphase anaphase telophase
1.primary oocytes
<span>- diploid (2 complete sets of chromosomes) </span>
<span>- 'formed' from oogonia during the process of oogenesis </span>
<span>* primordial follicles consist of a primary oocyte + a single layer of squamous follicle cells </span>
<span>* primary follicles consist of a primary oocyte + 1/several layers of cuboidal follicle cells </span>
<span>2. secondary oocytes </span>
<span>- haploid (1 complete set of chromosomes) </span>
<span>- developed from the primary oocyte undergoing meiosis I to form a secondary oocyte + a tiny first polar body </span>
<span>* found in the matured Graafian follicle </span>
<span>* begins meiosis II & stops at metaphase II upon ovulation & only continues upon fertilisation</span>
Answer:
High pressure systems entail sinking air, while lows entail rising air. High pressure systems form where air converges in the higher levels of the atmosphere. The converging air has nowhere to go and is forced to sink toward the ground. ... In contrast, low pressure systems form where air near the ground converges.

Answer:
Option-1 and 3
Explanation:
Cadherin is the protein complex present in the cell which is responsible for the sticking together of cell in tissue-like in the skin. The cadherin junctions allow the communication between the cells and the loss of the cadherin could cause cancer.
The cadherin junction is involved in the signalling pathway in the cells like in the Rho GTPase signalling, Ras signalling and many others which shows that they are responsible for the biological processes in an organism.
Thus, Option-1 and 3 are correct.
