Answer:
Cenozoic era refers to the geological time period that extends from 65 million years ago to present-day.
The current era is Cenozoic era. Therefore, option (D) is correct.
What is Cenozoic era?The Cenozoic era started around 66 million years ago and is also known as the Age of Mammals because it is characterized by the diversification and dominance of mammalian life on Earth during that time. The Cenozoic era began around 66 million years ago. Following the Mesozoic era, also known as the Age of Dinosaurs, and the Paleozoic era, which came before it, the Cenozoic era is the third and most recent era of the Phanerozoic Eon (Age of Invertebrates).
The Cenozoic era can be further subdivided into three distinct periods: the Paleogene, the Neogene, and the Quaternary. The Quaternary period, which began approximately 2.6 million years ago and is characterized by the occurrence of ice ages and the evolution of early humans, is the period in which we are currently living..

Answer:
29.5 days
Explanation:
However, it takes our Moon about 29.5 days to complete one cycle of phases (from new Moon to new Moon). This is called the synodic month. The difference between the sidereal and synodic months occurs because as our Moon moves around Earth, the Earth also moves around our Sun.

Cells without a cell wall will form a_________to separate the cytoplasm in cytokinesis, while cells with a cell wall will form a ________to separate the cytoplasm in cytokinesis
Answer:
Contractile ring, sterols
Explanation:
In cells such as animal cells that lack cell walls, cytokinesis follows the onset of anaphase. A contractile ring composed of actin filaments forms just inside the plasma membrane at the former metaphase plate. The actin filaments pull the equator of the cell inward, forming a fissure.
Examples of bacteria that lack a cell wall are Mycoplasma and L-form bacteria. Mycoplasma is an important cause of disease in animals and is not affected by antibiotic treatments that target cell wall synthesis. Mycoplasma acquire cholesterol from the environment and form sterols to build their cytoplasmic membrane.
Hope this helps!

Cells without a cell wall will form a furrow to separate the cytoplasm in cytokinesis, while cells with a cell wall will form a cell plate to separate the cytoplasm in cytokinesis, as the cell division of the plant is different from the animal.
What is the significance of the cell wall?It has the structural components of the plant cell that surround the cell membrane of many types of cells and a protective barrier that supports and maintains the shape of the cell, and due to its rigidity, the cleavage furrow does not form but the cell plate is formed.
Hence, cells without a cell wall will form a furrow to separate the cytoplasm in cytokinesis, while cells with a cell wall will form a cell plate to separate the cytoplasm in cytokinesis, as the cell division of the plant is different from the animal.

What is the cellular mechanism of tuberculosis? (Explain)
Why do our bodies rearrange the food we eat and the oxygen we breathe (O2) into carbon dioxide (CO2) and water (H2O)?
a
In order to release the energy found in food.
b
In order to eliminate the calories found in food.
c
In order to remove excess water in the body.
d
In order to release the matter found in food.
Answer:
A. in order to release the energy found in food.
Explanation:
Every cell in your body needs oxygen to function. You get the oxygen your cells need from the air you breathe. The air you breathe is made up of 20 percent oxygen. The rest of the air is mostly nitrogen (79%). Your body cells use the oxygen you breathe to get energy from the food you eat. This process is called cellular respiration. During cellular respiration the cell uses oxygen to break down sugar. Breaking down sugar produces the energy your body needs. This is very similar to wood burning in a fire. As the wood burns, it combines with oxygen and releases heat energy and carbon dioxide. When the cell uses oxygen to break down sugar, oxygen is used, carbon dioxide is produced, and energy is released. But instead of heat energy, much of the energy produced in cellular respiration is stored chemically for the cell to use later. Carbon dioxide is the waste product of cellular respiration that you breathe out each time you breathe. Blood picks up oxygen and releases carbon dioxide in the lungs. The opposite takes place in the cells where the blood releases oxygen and picks up carbon dioxide.
