Answer: Both cell types will undergo aptosis
Explanation:
cells lacking both Bax and Bak, but not cells lacking only one of these components, are completely resistant to tBID-induced cytochrome c release and apoptosis. Moreover, doubly deficient cells are resistant to multiple apoptotic stimuli that act through disruption of mitochondrial function: staurosporine, ultraviolet radiation, growth factor deprivation, etoposide, and the endoplasmic reticulum stress stimuli thapsigargin and tunicamycin. Thus, activation of a “multidomain” proapoptotic member, BAX or BAK, appears to be an essential gateway to mitochondrial dysfunction required for cell death in response to diverse stimuli.
The Pasteur effect shows that yeast consume glucose at a higher rate under anaerobic conditions than under aerobic conditions. Which of the following statements correctly explains this observation?
A. Less ATP is made under anaerobic conditions, so more glucose must be consumed to produce an equivalent amount of ATP.
B. Yeast are photosynthetic, so they are able to produce their own oxygen.
C. This observation is incorrect.
D. Aerobic conditions mean that cells make more ATP and use more glucose.
E. Yeast are obligate anaerobes, so aerobic conditions will kill yeasts.

chloroplasts work to convert light energy of the sun into sugars that can be used by cells. Its like a solar panel that changes sunlight energy into electric energy. The entire process is called photosynthesis and it all depends on the little green chlorophyll molecules in each chloroplast.
Write down the functions of
1.microtubules
2.tripletsof microtubules
Answer:
Microtubules are filamentous intracellular structures that are responsible for various kinds of movements in all eukaryotic cells. Microtubules are involved in nucleic and cell division, organization of intracellular structure, and intracellular transport, as well as ciliary and flagellar motility
Centrioles are cylindrical structures that are made up of protein tubes called microtubules. Specifically, nine groups of three microtubules, known as triplet microtubules, are linked together to make the walls of the cylinder.
Hope it helps :)
Answer:
Microtubules have several functions. For example, they provide the rigid, organized components of the cytoskeleton that give shape to many cells, and they are major components of cilia and flagella (cellular locomotory projections). They participate in the formation of the spindle during cell division (mitosis).
triplet microtubules are linked together to make the walls of the cylinder.

Which of the following is an example of a
homologous trait?
A. the wings of bees and birds
B. the forearm of different animals
C. the DNA of land animals
Answer:
the wings on bees and birds
An example of a homologous trait is the wings of bees and birds. The correct option is A.
What are homologous traits?The Theory of Evolution can be used to explain the homologous features of related species. According to this hypothesis, species develop over time from a common progenitor.
In order to adapt to the new environment, species separated from one another and developed new features. The variety of species observed on Earth today is the result of a process known as speciation.
The homologous features that are shared by related species are proof of their shared ancestry. For instance, despite being different, the wings of a bat and a bird share characteristics.
Therefore, the correct option is A. the wings of bees and birds.

Classify these hypotheses about the ocean as falsifiable or non-falsifiable.
The hypotheses about the ocean as
Falsifiable: 1) Limestone erodes faster than basalt when exposed to ocean salt water 2) Shallower tide pools support more algae growth.
Non-falsifiable is: 1) The rugged Panama coastline offers a wonderful experience for fishing enthusiasts. 2) Warm ocean water is more enjoyable to swim in than cool ocean water.
Limestone erodes faster than basalt when exposed to ocean salt water.
This hypothesis is falsifiable. One could conduct an experiment in which samples of limestone and basalt are exposed to ocean salt water and the rate of erosion is measured and compared between the two samples.
The rugged Panama coastline offers a wonderful experience for fishing enthusiasts.
This hypothesis is non-falsifiable. The statement is subjective and cannot be tested or proven true or false. What one person considers a wonderful fishing experience may not be the same for another person.
Shallower tide pools support more algae growth.
This hypothesis is falsifiable. One could conduct an experiment in which algae growth is measured and compared between different depths of tide pools.
Warm ocean water is more enjoyable to swim in than cool ocean water.
This hypothesis is non-falsifiable. The statement is subjective and cannot be tested or proven true or false. What one person finds enjoyable may not be the same for another person.

Answer:
The correct answer is -
a. has a grossly enlarged face and hands compared to torso and limbs
c. is distorted because of the disproportionate representation of certain body parts relative to others in the somatosensory cortex
Explanation:
" Homunculus" is a graphical representation of a small but fully grown man which the foetus is believed to develop whereas somatosensory homunculus is a neurological representation of the brain of humans that shows the motor and sensory functions of the body.
It has a large number of sensory nerves from the hand that take a large part of the brain. The face also has many nerve endings and are represented by large areas of the homunculus. A distorted look comes from this uneven representation of different body parts in the homunculus.
