Answer:
Water is continuously cycled from land to the atmosphere and back.
Explanation:
Water is considered a renewable natural resource because of the water cycle. Water from streams, rivers, oceans, seas, ponds, and etc undergoes evaporation from land to the atmosphere. It later passes through the process of condensation; and come back in the form of precipitation.
Answer:
endothermic
Explanation:
A reaction in which energy is absorbed from the surroundings is called an endothermic reaction. In endothermic reactions the enthalpy of the products is greater than the enthalpy of the reactants. Because reactions release or absorb energy, they affect the temperature of their surroundings.
Answer: Oval.
Explanation:
The nucleus of a cell is a membranous structure normally found in the center of eukaryotic cells and is where most of the cellular genetic material is found, organized in DNA molecules (deoxyribonucleic acid) associated with proteins such as histones, which make up the chromosomes.
<u>The function of the nucleus is to maintain the integrity of the genes in the DNA and to regulate gene expression to control cellular activities</u>. It then controls when DNA is transcribed into RNA (ribonucleic acid) and when it is exported to the cytoplasm to be translated into proteins.
The nucleus is composed of a nuclear envelope consisting of a double membrane that surrounds it, as well as pores that allow the passage of RNA for the regulation of gene expression.
<u>The cells of the inner cheek are classified as non-keratinized stratified squamous epithelium</u>. An epithelium is a tissue made up of joined cells that line the outer surface of the body and inner organs. Squamous cells are flat, scale-like, whereas stratified cells are arranged in multiple layers. Non-keratinized means that the cells constitute soft tissue found in the moist parts of our body, such as the mouth, stomach, among others. In a normal healthy cell, the nucleus is uniformly stained, oval in shape and smaller in relation to the cytoplasm.
Answer:
D. 1900s
Explanation:
it laid the groundwork for advancements.
Answer:
50% or 1/2
Explanation:
The probability of their 6th child being a girl would be 50% or 1/2.
During meiosis, the female produces X eggs while the male produces X and Y sperms. A random fusion of gametes then occurs during fertilization.
XX x XY
XX (female) XY (male) XX (female) XY (male)
XX - 1/2 or 50%
XY - 1/2 or 50%
<em>Hence, the probability of producing a girl is 1/2 or 50% irrespective of the number of kids a couple might have produced already.</em>
